She slips an expensive Rolex around her wrist and slings a stylish $3,000 Gucci bag over her shoulder. A football star lavished her with these little luxuries, but now — after finally bedding the NFL player — she wants a car.

“With christmas coming, I think now is as good of time as any to throw that out there lol . . . Nothing major, just a CTS or a 535 or something . . . 40-50 thousand range,” writes a Brooklyn woman who goes by the handle “Angelina Yee.”

“I actually don’t think he’ll object but i don’t know how to go about this, especially with football season coming to an end soon and him leaving to go back to his home town.”

The Cadillac-coveting gold digger who dates Footballer X — a player in the north who hails from down south — posted her dilemma on BallerAlert.com, an online groupie site where jersey-chasing women often huddle to swap advice and scandalous dating stories.

So, what’s a girl to do if gift hint-dropping fails?

“I would say in a very deep seductive voice, look him in his eyes and then say, ‘baby you know what I want you to do for me? Buy me a 2011 (insert the car you want there). Then smile lick your lips or wink your eye and go on with your business,” advises Zaria 22.

“I usually do this [over] dessert or Ice Cream. Something that brings attention to the mouth [and] looks sexy.”

Pro athletes, beware — groupies have gone online to plot your bankruptcy. Unlike the aspiring mistress of yesteryear, who sharpened her elbows to sidle up to her favorite sportsman in a crowded venue, today’s tech-obsessed girls discuss outfits, strategies and even positions before the first encounter even occurs.

Today, players are less likely to meet girls at a strip club or bar than they are on Facebook — as was the case for two women who linked up and went on to bear children with New York Jets father of nine Antonio Cromartie.

And beware if you don’t come through with the BMW. The groupies are quick to shame, posting pictures of themselves in hotel rooms for wives to find, or revealing intimate details about someone’s off-field performance.

‘OFFICIAL Groupie,” a rosy cheeked Florida-based beauty, coaches inexperienced groupies on BallerAlert. First in her playbook: Chase after the dumb jock.

“See, the smarter ones are on to your gold digging groupie ass. The smart ones can smell your money-hungry ass a mile away,” the vixen posted in a three-part series, “How to Land a Baller.”

“You know the ones that can barely speak well in an interview,” Official Groupie instructs. “Yes, bitch, him! Write his name down. Google him!

“Start to focus on the ones who have criminal records, many baby mommas and plenty of kids, and have ‘advisors’ (i.e. cousins/homeboys that handle their business/money). They’ll be easy to recognize cause they always look ‘lost’ and ‘slow.’ He barely makes eye contact. He got a short attention span and easily gets distracted. He gotta think about the words he wanna use before he speaks and still mispronounce the words. He does stupid/dumb s – – – right in front of you. Yeah, him!”

On this ever-expanding online manual, girls who want to score with an athlete learn to blend old and new groupie tactics when it comes to bumping into a player.

BallerAlert’s “Eleven8,” for example, suggests memorizing the layout of the W Hotel in Hollywood, where, she said, the NBA stars will rest their heads during February’s All Star Weekend in Los Angeles.

Then modern girls equipped with a smartphone can take advantage of Eleven8’s “Twitter-holic Trick.”

“As proven by Carmelo Anthony and countless others, most ballers control their own Twitter accounts. Know their away schedules! When they’re going to be in LA this is the perfect time to turn on your cyber charm and tweet your favorite baller until he takes notice,” she writes.

“Most ballers usually follow groupies [on Twitter] right before they hit the city this way they can keep the conversation isolated. Once he’s in your [private] box you can get the digits and the hotel room number.”

Kansas City Chiefs wide receiver Dwayne Bowe dubbed this type of pre-arranged rendezvous “importing,” telling ESPN magazine in May that senior players compiled a starting lineup of groupies drafted from Facebook and Twitter before away games and flew the women out to the team’s hotels.

Time and time again, the public’s prying eyes discover stars’ exploits on social network sites. Bloggers at TheDirty.com make a sport of outing groupies. Last month they posted a screenshot of a Facebook page where two women boasted about an evening with Philadelphia Eagle Michael Vick.

“Swimming with Michael Vick and cuziie !!!,” exclaimed a woman named “Julia’s Status.”

“What a night/morning with him bahahahah. wait I just woke up next to Michael Vick,” her friend Lana writes.

The BallerAlert chicks also giggled when a woman named Tia dumped NFL star James Davis via her Facebook page in June.

“3 kids 3 baby mamas 6th round pick wat the f–k was I thinking. relationships r Def not ur strong point . . . hope u excel in FB its the only thing ur good at. someone please give James Davis the memo . . . his relationship is over,” the angry girlfriend wrote.

THE gabby girls on BallerAlert, how ever, tend to hush their specific dalliances, though some of the groupies dished in a compendium called the “bad baller list.” This do-not-date list discusses cringe-worthy bedroom behavior and faulty equipment and includes top names like Jets wide receiver Braylon Ed wards, Cincin nati Bengal Chad Ocho cinco, and Boston Celtics star Paul Pierce.

While that warning list reads like a private con versation be tween best friends, the fame-enam ored women adhere to a certain code, which, if broken, could ruin their game. Violators pay a price.

BallerAlert’s members lashed out at a novice groupie who posted boastful snapshots of her inside of Oakland Raider Darren McFadden’s room.

The girl, “Ashley,” broke the groupie commandments by posting shots of herself grinning next to his memorabilia and his identification and then spreading it online. Ashley shared a picture of him shirtless standing in front of what clearly is a hotel-room shower.

“DO NOT EVER sneak around a ‘ballers’ hotel room and take pictures with his team memorabilia, chain, name-tag, etc. (especially when he’s not there and then again don’t ask a ‘friend’ to take the pictures)!” rips member “Karman San Diego.”

“DO NOT EVER snoop in a ‘ballers’ belongings and then take pictures of the evidence (pictures of said ballers girlfriend/baby momma)!”

Ashley is no longer a member of the site.

High-tech groupies, like Yee, simply stick to blind items and advice trades.

After spending time with her baller, the Brooklyn groupie wondered how other girls felt about being a “teamer.”

“I’m seeing chics that mess with two, three or four different players on the same team and trying to figure out how they pull it off . . . or if the guys just don’t care lol,” she wrote.

So far, there’s no news of a bow-wrapped Cadillac parked outside of her condo. But, Angelina did solicit advice from her online girls earlier this month when her mystery man incurred a “season compromising” injury.

“Mrs. Denbeigh” offered pampering tips and tellingly added, “still keep it sexy with minimal clothes around the house and naughty pics when you’re away. As long as it’s not a ca reer-ending injury, play your position.”

BallerAlert girls share relationship advice.

* Problem: An NFLer dropped his digits, but now I don’t know how to stand out in the stands!

* Solution: On game day pair jeans with a tight team tee. “You need to go to the kids section so it can fit really cute,” suggests “Miss Bling.” Don’t forget to pack after-party clothes. “Get your ass to the after party and be the sexiest bitch in there! Sexy not slutty!”

* Problem: I don’t know how to contact my favorite sports star.

* Solution: Try Twitter or add Kik Messenger to your phone. “Athletes, as dumb as they are, have used this forum to add new hoes to their roster,” writes “Mrs. Denbeigh.” “It’s the way to get a number without actually giving a number, and arrange rendezvous via direct message.”

* Problem: Can this pro athlete afford me?

* Solution: First, check that baller’s salary. “According to NBA.com the minimum annual rookie salary is $442K so don’t sleep on the rookies,” one groupie advises.
