Ryan Reynolds has spent his birthday weekend with Blake Lively.
The 'Green Lantern' co-stars - who met on the set of the movie earlier this year - were spotted on Saturday morning (22.10.11) with their dogs outside an apartment block in Boston, where the actor, who turned 35 yesterday, is filming new action flick 'R.I.P.D'.
A source told People magazine: "They are very much a couple. They're really happy together."
However, this isn't the first time Blake - who recently split from Leonardo DiCaprio after five months of dating - has travelled to Boston to see Ryan, as the pair were reportedly spotted having a romantic dinner in exclusive Boston eatery Mistral Bistro last Monday (10.10.11).
A source said at the time: "It's getting more serious. Ryan really respects her."
Meanwhile, the 'Change Up' star - who split from wife Scarlett Johansson last December - headed to New York to visit Blake on the set of 'Gossip Girl' the previous weekend.
A source said: "They hugged and then got in a car together. They became good friends on the set [of 'Green Lantern']. Now they're both single and trying it out. They're seeing each other casually."
