Report: Ryan Reynolds Is ‘Really Happy’ With New Girlfriend Blake Lively

Blake Lively moves fast: just weeks after breaking up with Leonardo DiCaprio, Lively is reportedly getting serious with Ryan Reynolds. The "Gossip Girl" actress, whose increasingly high-profile dating life could be a juicy plot arc on the CW soap, joined Reynolds in Boston over the weekend to celebrate his 35th birthday. People.com has a photo of the "Green Lantern" co-stars-turned-boyfriend and girlfriend walking around Beantown with their dogs; Reynolds is filming the upcoming action-comedy R.I.P.D. in the city. (Just Jared's got another shot of Lively delivering a mysterious package on the set of the film.)

"They are very much a couple," an insider tells People.com. "They're really happy together."

It's tough to keep track of Ryan Reynolds' love connections: since divorcing Scarlett Johansson around this time last year, the actor has been linked to such hot commodities as Olivia Wilde, Charlize Theron and BFF Sandra Bullock. Late last month, Reynolds and Johansson rocked out together at a Radiohead concert in New York. Also in the audience: Blake Lively. While everyone was trying to figure out whether ScarJo and RyRy were on the path to reconciliation, RyRy and Blake-Blake -- all right, we'll stop -- were suddenly spotted making out on a train to Boston.

Hollywood is Hollyweird.
