WoW! MIMI and ha slayage...Queen of Da Work...Writing, Producing and Singing, now that is what I call PRODUCING!!!!!!!!!!!!!!!!!!!!

And they say these two aren't dependent on him.

Firework says hello

Is that the only hit he didn't produce for her?

He's so hot in the picture

If only he wasn't such a jerk

updated the OP, Katy now is Dr. Lukes latest #1 single, and Katy extends her lead to 8 #1's produced by king Luke

Thinking Of You , Waking Up In Vegas, & Firework

Mariah

Depends on whether you consider "Waking Up in Vegas" a hit.

The fact that almost all of her singles are Luke produced: 12/15 . Mostly of the Katy listeners don't realize that they (we) like Katy&Luke material the most while some are bashing him.

E.T.>>>>>>>>

Congrats

Despite what he did to Kesha, he's still one of the most talented producers of our time. Congrats to him. Now if he would stop treating women like crap.
