They've only been married for a few short months now, but it looks like Jennifer Aniston and Justin Theroux's marriage has hit a huge hurdle. There are new rumors suggesting the Hollywood star is worried that fellow actress Kristen Wiig is putting a huge dent on her marriage as she is reportedly getting a little too up close and personal with her husband.

According to the Hollywood Gossip on Tuesday, many eyewitnesses say that Wiig and Theroux have been seen flirting together on numerous occasions while promoting their new big screen offering, Zoolander 2. Sources say that their new friendship has left Aniston insecure and worse, totally jealous over Wiig.

One source dished, "Justin and Kristen have gotten closer since they made [the movie] together and Jen is very jealous. She's insecure, and the fact that Kristen is attractive and funny doesn't help!"

What's more, Aniston has supposedly noticed that her husband has been trying to spend all of his free time with his co-star, leaving her especially mad when he insisted on walking the red carpet with Wiig during the movie's premiere earlier this month.

The insider added, "Any hint of flirting will set Jen off."

So far a rep for Aniston has not made any comments about the report. The couple married in a quiet yet star-studded ceremony at home back in August of 2015. This is the first marriage for Theroux and the second for Aniston, who was previously married to Brad Pitt for five years before they divorced in 2005.
