Lively, Reynolds photographed together

A photographer for the agency Bauer-Griffin snapped a series of pictures early Saturday of a woman identified as Blake Lively leaving the Boston apartment of her "Green Lantern" co-star, Ryan Reynolds. The two actors have been the subject of relationship rumors since earlier this month, when Lively, 24, of TV's "Gossip Girl," broke up with film star Leonardo DiCaprio. Reynolds -- in Boston filming "R.I.P.D.," based on the Dark Horse Comics series -- brought his dog Baxter out in the still-dark morning to say goodbye to Blake and her dog before she entered a chauffeured SUV, the agency said on its website. Reynolds turned 35 Sunday.
