Leave it to Channing Tatum and Jamie Foxx to get the party started! The co-stars of “White House Down” just couldn’t help but start dancing during a photo call for the 5th Annual Summer Of Sony at the Ritz Carlton Hotel in Cancun, Mexico, on Friday night. They were joined by Maggie Gyllenhaal and director Roland Emmerich. Tatum and Foxx started dancing as soon as they stepped out of their car. Later, Tatum took Gyllenhaal for a little one-on-one whirl.
