Britney Spears Hangs Out With Lady Gaga, Hints At Collaboration:

Lady Gaga hit Las Vegas to check out Britney Spears’ residency at Planet Hollywood, and stuck around to pose for a photo with the “Work Bitch” singer.
On Tuesday, Britney teased the meeting by tweeting “Little bird told me something cool today. See you soon @LadyGaga ,”  with Gaga coyly responding “This lil’ birdie?”
Are the two pop divas planning to record a song together? Or perhaps Gaga will pop up at Planet
 Hollywood when her ArtRave tour comes to Sin City?
 We know one thing Britney is cooking up with Gaga—barbecue. Her dad, Jamie Spears gave Gaga some homemade BBQ, which she called “one of the best things I’ve ever eatin’ in my LIFE,” in a tweet.

The lovefest between the singers has gone on at least since Gaga wrote “Telephone” for the former Disney star. (It eventually wound up landing in Beyoncé’s hands.)  And in 2011, Mother Monster—in the guise of her male alter ego Jo Calderone—presented Britney with the Video Vanguard award at the MTV Video Music Awards.
