There's another report that says Theroux has also been getting chummy with his Leftovers co-star, 19-year-old actress Margaret Qualley.

According to In Touch Weekly's print edition this week (via Celebrity Dirty Laundry), Theroux has been spending a lot of time with Qualley, both on and off the set.

What's more, Aniston and her man have been forced to live thousands of miles apart, as she is currently in Atlanta filming her latest blockbuster hit while Theroux is in Texas filming the next season of The Leftovers.

So far, Aniston herself has not made any comments about the rumors.

The couple tied the knot back in August after a two-year long engagement. Aniston was previously married to Brad Pitt for five years while Theroux was in a 14-year relationship with makeup artist Heidi Bivens. Keep up with Enstars for all the latest news on your favorite Hollywood couples.
