Fergie and Quentin Tarantino celebrated their birthdays last Thursday night in Las Vegas.

“We wanted to do something that was crazy and a lot of fun,” she told Us magazine.

The pair — who filmed a hot and heavy love scene in Tarantino’s 2007 flick Grindhouse — spent the afternoon with friends at the Mirage Hotel’s Bare Pool Lounge.

Fergie (who turned 33) and Tarantino (who turned 45) caught the 7 p.m. performance of Cirque du Soleil’s, Beatles-themed show, “LOVE.”

Fergie and Quentin headed to Jet Nightclub to party the night away with their friends. Kid Rock showed off his DJ skills for the birthday girl and boy. The night ended when Fergie and Quentin started a food fight with the big fancy cake that rolled out around 2:30 a.m

Further putting those pregnancy rumors to rest, Fergie sipped on wine throughout the night.

Here are some pics from the party:
