Coming in first place is usually a good thing… unless you’re Ashton Kutcher and you landed the top spot on Lindsay Lohan’s list of a-list lovers.

But what does the 36-year-old’s top spot on the list mean for his relationship with fiancée Mila Kunis? According to a source who knows the former costars, it won’t be pretty for Ashton.

“Mila is definitely going to be jealous and upset,” a source says of the Friends With Benefits star. “She’s only human and has insecurities like everyone else.”

This is a normal reaction, according to marital and family therapist Beth Proudfoot—who never worked with Ashton and Mila—explained to In Touch, adding it could have a detrimental impact on their future wedding.

“This just takes away from the wedding,” she told the mag. “It isn’t about the bride at all anymore—it’s about his past. And you have to start to wonder about his judgment if he’s been involved with someone who’s such a train wreck.”

In Touch Weekly exclusively revealed the names of the Hollywood stars—such as Justin Timberlake, Adam Levine, Orlando Bloom and Zac Efron—on Lindsay Lohan’s personal conquest list.

The mag obtained the list from a source who saw the Mean Girls star scribble down the name and then toss it aside at the Beverly Hills Hotel in January 2013.

“It was her personal conquest list,” the source said. “She was trying to impress her friends with the list and then tossed it aside.”

A source close to the 27-year-old said the list isn’t surprising, given Lindsay’s unapologetic behavior when it comes to men.

“She loves being linked to good-looking, famous, successful men,” the insider told In Touch. “To her, that’s a measure of success. She thinks she’s Marilyn Monroe. She sees it like she’s this Hollywood bombshell who men couldn’t resist. She doesn’t care about the consequences her actions will have on other people because she lives in a fantasy world.”

While Lindsay is carefree when it comes to consequences, it seems Ashton and Mila may end up paying the ultimate price.

The source close to the engaged couple told In Touch that they’re trying to be “traditional” after his failed marriage to Demi Moore—he even approached her father for her hand in marriage before proposing in an effort to foster and maintain a stable, loving relationship.

But all of that could be at stake—thanks to Lindsay.

“Someone like Lindsay coming back up like this shakes the foundation of what they’re trying to build,” the insider said.
