Los Angeles, February 14, 2007 – Jennifer who? We finally found out what’s been behind Beyonce’s beatific attitude during this Oscar season brouhaha over her Dreamgirls costar Jennifer Hudson.

All this time, the pop star was waiting to unveil her sensational Sports Illustrated swimsuit cover. And at last night’s SI party celebrating the 2007 issue, Beyonce basked in the limelight, endlessly posing for photos, sopping up the adulation. She told the media types on the press line not to shout, and then couldn’t get enough of the flashbulbs. When one photographer told her that this was the “best photo op we’ve ever had”, Beyonce laughed, and then kept posing, with a big smile pasted on her face.

We couldn’t persuade her to change into one of the swimsuits from her apparel line, House of Deréon, that she wears in the magazine. However, Ms. Knowles said that she’s often asked to don bikinis for photo shoots, but was waiting for the right time.

The Pacific Design Center bash was packed with beautiful models, including Brazilian soccer great Ronaldo’s girlfriend Raica Oliveira, and Leonardo DiCaprio’s love interest Bar Refaeli. You can see a bit more of what those lucky guys see in the swimsuit issue.
