Beyonce Knowles may have gotten more than flowers for Valentine’s Day.

According to TMZ, the Yonce possibly picked up a side of Hep A at a Sports Illustrated Swimsuit Issue party. The singer — who is on this month’s cover — was the guest of honor at the February 14th bash catered by famed chef Wolfgang Puck.

The Los Angeles County Department of Public Health confirmed that an employee of Wolfgang Puck Catering was recently diagnosed with the disease, and has strongly urged anyone who attended the SI party, or any of the 13 other events catered by Puck between Feb. 1 – 20, to get an immune globulin shot by this afternoon to prevent illness from attacking their system.

The list of potentially exposed guests also includes Leonardo DiCaprio’s girlfriend, Bar Refaeli, and dozens of models.

A rep for Beyonce, 25, told TMZ that they “were looking into it.”

And by “looking into it,” they mean that Mathew Knowles is currently tearing the offending sous chef limb from limb.

Meanwhile, the swimsuit models probably don’t have anything to worry about. It’s not like they ate anything.

The singer and now movie star (”Dreamgirls”) posed on a Florida beach in a yellow-and-pink bikini by House of Dereon, the fashion label she started with her mother, Tina Knowles. There’s also a photo spread inside.

“The Dreamgirl As You’ve Never Seen Her,” a cover headline teases.

The 2007 swimsuit edition continues with the music theme inside, featuring scantily-clad models posing with Kanye West, Aerosmith, Kenny Chesney, Gnarls Barkley and Panic! At the Disco for the camera of lensman Steve Erle.
