While Britney Spears and Nicki Minaj have embarked on several professional collaborations of late, it's no secret that the divas also really like each other. The two are taking their upcoming joint venture—a 26-date tour—very seriously, and spending quality time together before they get stuck on a bus (with nowhere to hide) for nearly two months this summer. Following Minaj's opening set on the I Am Still Music tour with Lil Wayne at the Staples Center, Spears and boyfriend Jason Trawick hit up the after party at The Factory in West Hollywood on Friday night. The two hung in the VIP section along with Khloe Kardashian (we can't wait for that remix. Make it happen, Kris Jenner!), while Spears chatted and posed for pictures with her favorite Barbie. The Femme Fatale tour kicks off on June 16 in Sacramento, Calif. Just look at all the fun you could be having, Enrique!

But don't expect the duo to stay up late gossiping over pints of Ben & Jerry's while on the road. Britain's The Sun reports that all junk food has been banned from the upcoming tour, including pizza, hot dogs, cookie dough ice cream, and beer. Maybe Enrique made the right choice after all.
