Mario Lopez hit the red carpet for the first time as the host of "Extra" -- and his celebrity pals remarked on his famous physique!
"I wanted to talk you about my abs," P. Diddy joked. "Can I talk to you personally? I'm trying to get my abs right." Charlie Sheen also kibbitzed with Mario about his toned body, saying, "Now the rest of us are in the gym... struggling like there's no hope, and you're like the benchmark. Thank you!"
Lopez wasn't the only one asking questions on the red carpet. "Extra" played Emmy CelebDegrees -- and let the stars put each other in the hotseat. "Grey's Anatomy" star Sandra Oh asked comedienne Cheryl Hines about her bra size, to which Hines said, "34... sad... 34B or A. It's really an A, but I say B to make me feel better."
