Aniston and Theroux, who have been living apart for the past few weeks, recently reunited in North Carolina to celebrate his 41st birthday.

The actress has been busy filming “We're the Millers” alongside her ‘Horrible Bosses’ co-star Jason Sudeikis in Wilmington, North Carolina, whereas Theroux has been traveling between New York and Los Angeles.

Aniston’s representative told a leading media tabloid, “It’s once again just another fabrication to sell magazines and has no relationship to reality.”

A magazine reported Theroux had dinner with a “mystery blonde,” who turned out to be his friend Amy Sedaris, according to an Us Weekly source.

The couple, who have been dating since May 2011, were last seen together on their tour of Europe in June. The “Friends” star whisked her man away on a romantic break to Paris, followed by a luxury stay on the island of Capri.
