Def Jam VP of A&R Bu Thiam had one of the best seats in the house at last night’s MTV VMA Awards. Bu sat in the front row right next to his client, singer Chris Brown, who won Best Male video of the year. But when Pink took to the stage to sing her hit “Blow Me (One Last Kiss),” Bu leaned into Chris and asked “Who is this?”

Brown didn’t hesitate to respond, “Pink,” he said.

Loyal reader ZimboChick (who reads lips) caught the exchange between Bu and Chris.

I was surprised that as long as Pink has been on the scene – and as long as she has been performing at these award shows, for Bu not to recognize her or at least know her song especially since he is one of the leading music industry icons!!!

I refused to believe Bu didn’t know who Pink was — until I watched the video of Pink’s performance for myself.

In Bu’s defense, he didn’t recognize Pink because she looked so different with her blond power Mohawk and slimmed down shape.

Watch the exchange between Bu and Chris, around the 1:03 minute mark, after the break!
