In a new YouTube video posted late Thursday night, Kelly Rowland and Michelle Williams goof around at a hotel in Manhattan. But if the singers are in town for Beyonce's rumored wedding, they're not saying.

"We're ... out of town," jokes Rowland, to which Williams chimes in, "At an undisclosed location," before Rowland admits that they're at the Four Seasons in New York – just a cab ride away from Scarsdale, where Beyoncé and Jay-Z got a marriage license on Tuesday.

Fresh off a plane from London, Rowland talks about performing at the Choice FM 18th Anniversary Party along with Mariah Carey and Ciara, and giggles while getting chased around the suite by Williams, who was in NYC for a listening session for her new album, Unexpected. "This is what happens when sisters get together!" says Rowland.

So where's Beyoncé? "B's in the studio tonight," says Rowland, adding that she's headed to Denver this weekend "to go see some friends" before heading to New Orleans for a show.
