Alexander Skarsgard celebrated his magazine cover at BlackBook's 15 Year Anniversary with Tequila Don Julio and Heineken at PH-D Rooftop Lounge at the Dream hotel in NYC last night. He actually shares the honor with his Straw Dogs costar Kate Bosworth, but she wasn't on hand for the bash. Kate and Alex, who started dating while making the movie, recently split up and have been handling their press solo. Alexander was able to party with the publication since he's in the Big Apple shooting What Maisie Knew. He logged a long day on the set and didn't do any interviews, but his True Blood castmate Kristin Bauer was happy to talk about how close their HBO family has become while working together. Kristin told us she came out just to support Alexander! How to Make It in America's Bryan Greenberg also turned out and shared a little about his excitement for Fashion Week. Bryan said, "I'm going to check out a couple shows. I'm also playing my music. I'm doing a little East Coast tour — that's part of the reason I'm out here . . . just here to do a little research and check out the whole fashion world since I'm still learning about it."
