*In a special Thanksgiving performance for radio station Hot 97, Nicki MInaj showed off exactly why she is rumored to have buttock enhancements.

The rapper wore a two-faced suit from fashion designer The Blonds – the front half was a normal black silk suit while the back half was a nude bejeweled body suit – as she performed at the Hammerstein Ballroom in her home town of New York with a host of friends, including Rihanna, Kanye West, Keyshia Cole and Drake.

In other news from the Hot 97 concert, Rihanna grabbed Nicki’s ass for the second time in five days.

The first instance took place Sunday at the American Music Awards. [See photo below.]

Grab No. 2 happened on Thanksgiving.  After the two performed their duet “Fly” at the Hammerstein Ballroom, RiRi embraced Minaj under her buttocks and squeezed upward. Minaj said afterward, “She’s the only one who can get away with doing that.”
