Pregnant Beyoncé Knowles was in a long green dress yesterday for a bash held at Alex Rodriguez's Miami home. Alex himself was seen hanging out with his guests at the house, which ex-girlfriend Cameron Diaz was a regular at before their breakup a few months ago. Beyoncé headed to Florida after a stint in NYC with her husband Jay-Z. Both Jay and Beyoncé are in the Sunshine State as his Watch the Throne tour moves through the South. He and Kanye West will perform in Sunrise, FL, today, and tomorrow brings a show in Miami. This weekend, though, the gang moves back toward the Big Apple for a Saturday gig in Atlantic City.
