Does Lady Gaga Guest Star On Rihanna's Loud?

Image of forthcoming album's back cover allegedly leaks online, contains collaboration called "Broken Heels."

Separately, Rihanna and Lady Gaga have tallied more #1s on the Billboard Pop Songs chart than any other artists, so you can probably imagine what would happen if they were ever to team up on a track.

Well, forget about the imagine part. From the looks of things, RiRi and Gaga are joining forces on Rihanna's upcoming album Loud.

This is according to what appears to be the official track listing for Loud, which was revealed in a

That track listing contains a song called "Broken Heels," on which Gaga is featured. Other cameos on the album include Rihanna's almost-tourmate Nicki Minaj (on a track called "Raining Men"), ("Bubble Pop") and — confirming earlier reports — Drake, who guests on "What's My Name?"

It's all very exciting. But is any of it actually real? Well, it bears noting that all of the tracks mentioned in Just Jared's early review of the album ("S&M," "Cheers," "Man Down," "California King (Bed)," "Fading Away" and "Raining Men") do show up on the back cover in question ... but it also bears noting that the ballad "Straight Up Beautiful," which Rihanna herself mentioned just last week, does not.

Fans will have to wait until November 16, when Loud hits stores, to find out for sure. At press time, a spokesperson for Rihanna had not responded to MTV News' request for comment on the Gaga collaboration.
