Britney Spears and Jason Trawick dropped in to surprise Nicki Minaj at her show and give fans a great celebrity sighting at The Factory in LA Friday night. Britney was all smiles to snap a few photos with her Femme Fatale tour mate, Nicki, and mingle with Khloe Kardashian in the VIP area, though Britney and Jason left after just 30 minutes. Britney and Nicki's mega tour kicks off June 17, but the singers have already teamed up on a new remix, which also includes Ke$ha, of Britney's "Till the World Ends." It's the second remix release this month for Brit who also worked with Rihanna on a tricked out version of "S&M."
