Rachel McAdams and Ryan Gosling are "definitely together again."
The pair - who split last April after dating for two years - are celebrating their rekindled relationship with a holiday in Toronto, Canada.
Gossip blogger Perez Hilton said: "Sources have revealed exclusively to me that Ryan and Rachel are definitely together again. They are on holiday in Toronto and are both very happy."
The couple, who are both Canadian, are in the city ahead of the annual Toronto International Film Festival which runs from September 4 to 13.
Ryan and Rachel - who co-starred in 2004 movie 'The Notebook - first sparked rumors they were back together when Rachel was spotted at Los Angeles' Green Door lounge, where the actor made his DJ debut last month.
An onlooker said: "Rachel and Ryan talked when he was away from the deejay stand. They really looked like good pals. He seemed happy to see her."
