When it comes to kissing other female pop stars, Britney Spears draws the line at Lady Gaga.
Spears infamously locked lips with Madonna during the 2003 Video Music Awards -- but apparently she wasn't down for a repeat performance during last night's ceremony.

"I've done that already" she said, while laughing at the podium.
