According to reports, Jennifer Aniston and Justin Theroux's relationship is in trouble because of The Leftovers actor's philandering ways.
According to a magazine, Theroux was caught flirting with Girls star Allison Williams during the Emmy Awards ceremony last month.
An eyewitness told Life & Style, "He twirled a cigarette, joked and flirted with her."
The actor was on a flirting spree and was reportedly trying to play coy with Paula Patton, who split with Robin Thicke early this year.
"They huddled so close, their lips almost met," the party guest told the magazine. "After friends tipped Jen off about his behavior, she ripped him a new one," added the insider.
The report is fuelling break up rumours, although there is no confirmation whether the wedding is off.
Also, Aniston's marriage plans are under heavy media scrutiny this year, especially since her ex-husband Brad Pitt married Angelina Jolie in a secret ceremony.
Recently, in an interview the Friends star was asked if the marriage date is set. She laughed and replied, "I don't know!"
In an interview with Today, the 45-year-old actress talked about the institution of marriage.
She said, "I just think you live in the moment, you're with someone, I think you learn as you get older, too... marriage is a wonderful thing, a relationship is a wonderful thing; it's a way to discover who you are."
"My life is a happy life," she said. "It's a choice. Justin is probably one of the funniest human beings that I've ever encountered," she added.
"I have the great fortune to laugh a lot. We laugh a lot."
