Seventeen Magazine threw a party to celebrate singer Beyonce’s cover story. Sasha is also the magazine’s “2008 Style Star of the Year.”

In a recent interview with Power 105.1’s The Ed Lover Show, Beyonce talked about the skit she and Justin Timberlake did last weekend on NBC’s Saturday Night Live.

“I still can’t believe he did that. He was incredible,” Beyonce said. “We rehearsed it two times. He picked up the choreography. He has this photographic memory. He could probably kill it if he wanted to.”

We would pay to see Justin Timberlake re-enact the entire Single Ladies video! For more photos of Beyonce at the Seventeen Magazine party … you know what to do.
