The trio was spotted exchanging kisses and hugs after a nice dinner at Mr. Chows restaurant in Beverly Hills, California.
Tamar tweeted about the fun-filled meal by letting her followers know just how hysterical Gags really is.
"A #funners dinner with @tonibraxton @ladygaga and my hunny bunch! I wish u all were there for the kiiiiiiiiiiii at THAT table! #realfun"
We're willing to bet the most fun part was looking at Gaga's nipples all night long! We're not exactly sure why the gals were dining together - maybe there's a new collaborative project in the works?
Check out the pictures of last night's nipple-fest.
