The "SexyBack" singer did some table-hopping in the club's VIP area and had a brief chat with Federline, who occupied a table with Taye Diggs, Scott Storch and former football star Jamal Anderson. (Earlier in the evening Federline's Nationwide Insurance commercial made its national television debut at the Super Bowl.)
This isn't the first time Spear's exes have partied in the same city. Just last month, both Timberlake and Federline were in Las Vegas at the same time. Their paths briefly crossed then when Federline, along with Alyssa Milano, David Hasselhoff and Toni Braxton, caught Timberlake's show at the MGM Grand.
