On Sunday night at the 2011 Video Music Awards, [artist id="3061469"]Lady Gaga[/artist]'s alter ego Jo Calderone met the [article id="1669862"]princess of pop herself, Britney Spears[/article]. Gaga, in [article id="1669843"]full drag as Calderone[/article], and Spears had a bit of a VMA romance, sharing kind words -- and even swapping spit.

"It was interesting, her character," Spears later told MTV News about the encounter, even dishing how the kiss between the two took place. "We got onstage and we felt it out."

Spears, of course, has already kissed a famous pop star on the VMA stage, when she and Madonna locked lips back in 2003. And it's that kind of free spirit that Calderone noted in his speech about the singer. "She taught us all how to be fearless, and the industry wouldn't be the same without her," Calderone said when he not only kicked off the tribute to the star, but also later presented her with the Michael Jackson Video Vanguard Award.

After a troupe of dancers, who performed dance routines to everything from " ... Baby One More Time" and "Crazy" to "Toxic" and "Do Somethin'," left the stage, Calderone and Spears came face to face, and lips to lips. Although Spears seemed fine with the initial kiss, when he tried to make a few more advances, Spears rebuffed him with a big smile on her face.

He took it like a gentleman, adding, "I don't want Gaga to get pissed."

So was Gaga completely Calderone the whole time? "She's in full character," Spears later added. "Yes, definitely."
