“Awesome dad! way to make the thomas family proud.”

Brooklyn stroller dad of four William “Will” Thomas lived a double life as a doting father and neighborhood nice guy in Fort Greene — while also running a string of sleazy Manhattan brothels catering to johns hot for busty Asian women, authorities and neighbors said yesterday.

Thomas’ neighbors were stunned by the news — and his own teenage son even knocked the alleged Mr. Mom-turned-Pimp-Daddy on Twitter.

In addition to the snarky “Awesome dad!’’ remark, the 11th-grader tweeted, “My dad is the upcoming story on nbc news if anyone wants to watch . . .

“Pretty surreal to hear your dad’s name on the news in connection to a massive prostitution ring bust. had to happen eventually i guess.”

Thomas, 42, a former IT-company whiz, was busted this month for allegedly running four brothels, from the Financial District to the Upper East Side, for clients ranging from Wall Street suits to Hasidim in religious garb.

He had been quietly living in a first-floor apartment across from Cuyler Gore Park with his year-old son, the boy’s mother and his 3-year-old daughter by his second ex-wife, neighbors and relatives said.

Thomas also has two teenage sons from his first marriage, relatives said.

“There was nothing suspicious or anything,” one Fort Greene neighbor said.

Thomas — once a suburban businessman with a tony home in Branchburg, NJ — “is a nice guy, very friendly, always says hello,’’ added another resident who was in the park.

“He’s a regular here. He comes every morning at 7 or 8 with the baby. He does exercises.’’

The accused prostitution-ring leader frequents the Superior Markets deli a block away on Greene Avenue and “comes in with his kids, buys milk, talks about the [latest football] game,’’ a worker there said.

But at the same time, Thomas was allegedly using his ace computer skills to ramp up two raunchy Web sites featuring topless women — and promote his hooker biz, where sex romps ran $200 to $300 an hour.

He oversaw four brothels: on Maiden Lane, Sixth Avenue near 37th Street, East 50th Street and East 58th Street, authorities said.

The boyishly handsome suspect appeared to easily juggle his lurid secret life with parent duty, which included taking his 11th-grader to a Brooklyn Nets game on Friday at the Barclays Center.

The boy excitedly tweeted about how he and his dad had front-row seats.

The teen also posted a photo that same night of him and his father on the CBS-TV news set in Manhattan, posing with smiling meteorologist Lonnie Quinn, anchor Chris Wragge and sports editor Otis Livingston.

Thomas had once led a typical, middle-class life with then-first wife, Susan, and their two sons in Somerset County, NJ, friends said.

He made a good living working as an IT specialist at the tech firm Compuware.

“He was very successful. There was no need for him to go into the business he did,” said a source familiar with the family’s situation.

It’s unclear if Thomas left his IT job or was fired. In 2006, Susan divorced him, records show. She declined to comment on the arrest of her ex — who, according to records, is more than $100,000 behind in child-support payments.

Around the same time as the divorce, he began dating a Chinese woman in New York City.

But the relationship soured in a battle over a wedding ring, and in 2007, Thomas married his second wife, So Young, a half-Korean stunner who allegedly had connections that Thomas needed for his illicit new venture, a source said.

He divorced Young in March after the pair had a daughter, now 3 — and he had taken up with his current flame, a Japanese woman, one source said.

Young moved out of the country last year, the source said, leaving him to care for the child.

Thomas’ mother — Sheila Thomas, 64, a model and actress who has appeared in flicks such as Matt Damon’s “The Good Shepherd’’ — was in denial when recently confronted with the possibility her son might be involved in something illicit, said a source with knowledge of the family.

But cops said they have the goods on him, thanks to an undercover officer who posed as a john, met Thomas in a car on West 36th Street, and was directed to one of his low-rent brothels, a first-floor duplex at 238 E. 50th St., authorities said.

Thomas’ ring has been operating at least since September 2011, a criminal complaint said.
