Arie Luyendyk Jr.’s ex-girlfriend Cassie Harshman claims that he's been leading on The Bachelorette star Emily Maynard, and urges her to make a run for it.

If she even chooses him, that is. Arie and Jef Holm are the last two men standing. For insight on who she (likely) picks, read The Bachelorette spoilers.

In any case, “Arie’s in it for the fame,” at least according to Cassie, who claims “Arie has dated hundreds of women and travels all over the world."

“Clearly, he doesn’t need help finding a date or someone to fall in love with. The whole idea of Arie Luyendyk being on The Bachelorette is a joke."

"He hasn’t really raced much since 2008, and I know with certainty that his only motive for going on the show was for the fame and attention.”

Cassie Harshman - not to be confused with Cassie Lambert, The Bachelorette producer he also dated - began dating the 30-year-old in late 2009.

He ended up moving in with her and her two young children from a previous relationship. Arie and Cassie broke up for good in December 2011.

“He wasn’t the best father figure to my children,” says Cassie, something Emily may want to take note of, she says, given her seven-year-old girl.

“Let’s just say that Arie has some growing up to do himself.”

A previous report claims he was filmed on The Bachelorette telling Emily that Cassie miscarried his child; if so, this was edited out of the broadcast.

“If that happened, I’m mortified that Arie would share such painfully intimate details of our relationship while the cameras were rolling,” Cassie says.

“What happened is one of the hardest things a woman can go through. I’ve moved on, but Arie using that to elicit sympathy from Emily is horrible.”

Cassie Harshman's interview with Star/Radar should be taken with a grain of salt, of course. Motives for talking to them are highly questionable.

Still, let us know what you think in the comments below, and tell us who you think Emily should pick on the July 22 season finale in the poll:
