Frasier Is Back!

He’s back in the saddle!

Kelsey Grammer‘s not going to let his heart problems slow him down!

On Tuesday, he was hard at work (and making $$$$$$$$$) on a new Dr. Pepper commercial.

PerezHilton.com got these exclusive pix of Kelsey on the set.

He reprised his Dr. Frasier Crane role for the commercial shoot.

Fun!
