Robin Thicke and Nicki Minaj made an appearance on the Late Show with David Letterman, where they performed Thicke’s latest single “Shakin’ It 4 Daddy”. Although this performance was much better then the 1st one (on 106th and Park) I don’t think Nicki looked too good doing the choreography that was assigned to her. She can barely whine her body…and Robin should just stick to singing. Not to mention the little joke Letterman made in regards to him not needing to know about Sex Therapy…I don’t think he should have poked fun at his cheating ways. It was still a pretty cool performance though lol…Peep it below!
