Rachel McAdams and Michael Sheen have ended their relationship, it has been reported.
According to Us Weekly, the actress and the 44-year-old British star have called time on their relationship after two years together.
The 34-year-old beauty first met Michael when they worked on Woody Allen's critically-acclaimed movie Midnight in Paris in July 2010.
The couple took their relationship public in October of the same year.
The reasons behind the reported break-up are as yet unknown.
It is speculated that the long-distance aspect of their romance may have been a problem.
Rachel spoke about her relationship with Michael in January 2012, explaining their romance came about naturally.
"Michael and I didn't get together while we were filming Midnight in Paris, which I feel strongly about not doing when I'm working. We became quite good friends, which I think is a great way to start," Rachel revealed at the time.
"I felt very blessed to have made a Woody Allen film in Paris together."
The star hinted at difficulties the couple were facing as a result of Michael residing in Los Angeles and Wales, while she is based in Toronto, Canada.
"Michael and I never spend more than three weeks apart - we rack up a lot of air miles - but you have to be quite adaptable in this business whether you are in a relationship or not," she said.
"Trying to establish roots somewhere is a bit of a joke."
Rachel's last serious relationship was with fellow Canadian actor Ryan Gosling, who she dated from 2005 until 2007.
Following their split, Ryan described her as "one of the great loves of [his] life".
Michael has previously dated actress Kate Beckinsale, who he has a daughter with.
