Jennifer Aniston has denied the rumours that she started dating current beau Justin Theroux while they were working on their film 'Wanderlust'.
The former Friends actress were first romantically linked when they began filming the David Wain film last Spring.
Jen, 43, explained on Good Morning America that the pair had actually known each other for a while but nothing had happened on the set of their movie.
"Nothing happened on [Wanderlust]. I mean, that was sort of - that's what is a rumour. I mean, it's again, it's the easy rumour," she explained.
"Nothing happened. We were just friends, great friends, on the movie."
The actress continued: "I've known Justin for a long time… we met when he was shooting Tropic Thunder [years ago]… He is really cute."
Last year, Jen reportedly met up with Justin's ex-girlfriend of 14 years, Heidi Bivens.
In November the pair met up at a New York hotel and discussed what happened over a glass of wine. Jen was allegedly upset that she had been labelled a "homewrecker" and was keen to set the record straight.
According to Grazia, a source said: "Jen has always been sympathetic to Heidi because he's heard from Justin just how devastated she is about their break-up. But Jen has always been adamant that their relationships did not cross over."
The insider continued: "Jen told Heidi that she understands what a painful time she has been going through and explained that she wanted her to know, hand on heart, that she would never steal another woman's man.
"Heidi apparently got quite tearful during the meeting, as it was understandably a lot of take in."
Jen and Justin, who are living together, became a couple in May last year but in mid-June, Bivens issued a statement which said that she had "just moved out of their home last week", just one week after the couple were pictured together at the MTV Movie Awards after-party.
