The duo was escorted inside by security so that Theroux could tape a segment for Thursday's (February 23) episode of "Jimmy KLimmel Live!" - in which he's promoting his new movie "Wanderlust," which also stars Miss Aniston.
The studio visit comes after Jen made an appearance earlier today on "Good Morning America," during which she cleared up a pesky rumor regarding her current beau Justin Theroux and the timing of their relationship.
When asked by anchor Lara Spencer if she and Justin got together during the filming of “Wanderlust,” Aniston told, “Nothing happened on that movie… [That's] the easy rumor.”
“We were just friends,” she explained, adding, “I’ve known Justin for a long time.”
