AceShowbiz - Nicole and Mahmoud's shaky marriage was featured in a new episode of "90 Day Fiance: Happily Ever After?". Just one day after Mahmoud started his life in America, he upset Nicole that she threatened to send him back to Egypt.

The two were involved in an epic fight in the Sunday, March 31 episode of the TLC show. The argument started after Nicole caught Mahmoud seemingly checking out another Muslim woman right in front of her.

In the episode, Mahmoud and Nicole went to Santa Monica to spend the day at the beach after they returned to Los Angeles from Egypt. "I definitely took my country for granted when I moved to Egypt," Nicole shared during a confessional. "I just love it. I love everything about it -- because anything goes here."

Mahmoud, however, didn't really like America. "It's the first day so it's hard on me," he told her. Nicole said that she understood that Mahmoud might miss his family, but she added, "I'm just hoping that eventually he'll feel comfortable here."

Their Santa Monica date quickly took a sour turn when Mahmoud looked at another woman who wore a hijab. "You stopped dead in your tracks. ... I saw what happened," Nicole called him out. "You know what, like, if you want an Arab woman, you should go get one."

"I've been married to the man for so long, I know when he gets excited. And my husband is stopping dead in his tracks to stare at this woman," Nicole explained to cameras. "It definitely triggered some insecurities. It made me feel like I'm not good enough, like, maybe I'm not Muslim enough for him."

"After that little incident Mahmoud, I'm f**king putting your a** back on a f**king plane, and you go back to Egypt," she further ranted. "I don't care. If you want to be a little womanizer you can go back to f**king Egypt." That shocked Mahmoud, who later walked off.
