Sienna Miller must be taking a vacation from filming The Best Time of Our Lives since she's currently in NYC with her boyfriend Jamie Burke. The two are pretty tight these days, which is apparently causing problems with his band, Bloody Social. "The rest of the band is upset because no one talks about them - it's all about Jamie, and it's all because of Sienna," says a source. Maybe the band should be thankful since she's helping them get some free press. Wherever Sienna goes, headlines follow.
