Adam Levine, Behati Prinsloo Split? Flirting Outside Marriage Sparks Cheating/Divorce Scandal

Before tying the knot with stunning Victoria's Secret model Behati Prinsloo, Maroon 5 rocker Adam Levine was labeled an infamous Hollywood "playboy." The 36-year-old singer remains very flirtatious with other women, and now rumors suggest his marriage is faultering because of such shady behavior.

The "Sugar" crooner proposed to 26-year-old Prinsloo in July 2013 despite their on-and-off again courtship. They married the next year in Mexico, and just celebrated their romantic one-year anniversary on July 19 (2015). But is the blonde bombshell already worried that her new hubby might be cheating?

An alleged insider tells the seedy gossip tabloid InTouch:

"Adam's acting like the same playboy he was before they wed, and that's a problem for his wife... She thinks it's disrespectful for him to flirt with other girls when he's married to her."

Do MstarsNews readers agree that Prinsloo should be so suspicious?

Levine's "Hollywood" lifestyle could ultimately ruin his budding relationship with Prinsloo:

"He goes out all the time and hangs out with other models," the source continues. "Recently, Adam had a guys' night out and Behati found out he was chatting up girls. She was livid and they had a huge fight. It's a sore spot for her."

Maybe the Namibian beauty wants to settle-down and start a family soon? If so, "The Voice" superstar better get his stuff together - no more "innocent" flirting with other gorgeous fashionistas!

"She never wanted to be that nagging wife, but now she is, constantly calling or texting Adam to see where he's at. It's driving him crazy-and pushing him further away," the snitch concludes. "He promised Behati that after they got married, things would change - and they haven't."

Hopefully such break-up buzz is all silly hearsay - Prinsloo seems happy enough on Instagram!
