Fox is striking while the iron is Instagram pictures are hot!

Rihanna will perform on American Idol for the third time when she sings her HUGE single Where Have You Been on the two hour season finale.

The track already smashed Youtube records, brought the house down at SNL, and now RiRi will sing it while Hollie Cavanagh, Joshua Ledet, Phillip Phillips and Jessica Sanchez compete for the 11th season crown.

Idol crushed The Voice in the ratings last week and we imagine even more people will tune in to watch for a winner on May 23.

Hmmm.

How many of the show’s 16 million viewers do U think our girl will try and turn bi?? LOLz!!
