Despite being married to gorgeous model Behati Prinsloo, Adam Levine has purportedly not given up his life as a ladies' man, and his wife is not happy about it.

According to rumors, Adam Levine land his wife are having relationship troubles because the Maroon 5 front man is allegedly flirting with other women.

"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," a source reportedly told In Touch magazine, as quoted by Inquisitr.

"He goes out all the time and hangs out with other models," the source dished out. "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."

Apparently, Adam Levine's wife is aware of her husband's tendency to flirt, causing her to be jealous and paranoid.

"Behati has had trust issues. She never wanted to be that nagging wife, but now she is, constantly calling or texting Adam to see where he's at," the source stated.

Is it possible that Adam Levine has been flirting with his model ex-girlfriends, making his wife insecure about how strong their marriage actually is?

Before Adam Levine married Behati Prinsloo, Us Weekly reported that the "The Voice" mentor apologized to his ex-girlfriends, including models Anne Vyalitsyna and Nina Agdal, about how things got sour between them.

Entertainment Tonight previously recounted Adam Levine's relationships with models before finally settling down with Behati Prinsloo.

"Adam has been linked to an array of models," ET Online reported. "Including Janine Habeck, Angela Bellotte, and Nina Agdal.

"But perhaps his most public relationship was with Victoria's Secret model Anne Vyalitsyna, also known as Anne V., from 2010 to 2012. She appeared in the Maroon 5 music video for Misery, and Adam performed alongside her at the 2011 Victoria's Secret Fashion Show."
