Sure sounds like it!
Over the weekend, Mother Monster attended Britney's show and posted this behind-the-scenes pic of them palling around with the caption "Me and Brit Brit <3
She also said that they had a "Monster Party," which might have been centered around planning a diva duet.
According to Us Weekly, the two discussed the duet backstage and a source tells the site "It'll happen soon."
Not soon enough, we say!
We can't wait to hear what these two pop stars come up with when they collaborate.
Both singers have been hitting the collabs hard lately, with Britney recently teaming up with her sister Jamie Lynn Spears for one song on her 'Britney Jean' album and Miley Cyrus for a song on Miley's most recent album.
As for Gaga, she did a duet with Cher, which she didn't want to make public, but it leaked online anyway and she also did a duet with R. Kelly for her 'ARTPOP' album.
Now, the only question is, does this mean we can expect another new album from one...or both...of them, or will it just be a single?
