Touch Little Mix
Mother Monster showed up at Britney's gig last week and the pair got very pally.
After the show Lady Gaga went backstage to meet Britney Spears and was extremely friendly.
"Girl you're so damn hot," Lady Gaga told Britney. "I Would."
Not only did Gaga show plenty of love for Brit's looks, after chatting and dancing together, they got down to discussing a musical hook up.
"They sat for around an hour gossiping and talking about collaborating on a track together," a source told The Sun.
"Gaga already has two songs in mind.
"They even spoke about getting her down to one of Britney's later performances in October if she could schedule it to duet with her on stage."
