Jimmy Kimmel's parking lot security guard hilarious sidekick hit the red carpet of the Grammys to schmooze with the stars. More precisely, Guillermo teased and tormented them. The resulting footage was on full display on 'Jimmy Kimmel Live' (weeknights, 12AM ET on ABC). Since Valentine's Day was around the corner, he handed roses to the ladies (such as Miley Cyrus) and a few coupons for a free massage that "expires in one minute." He offered a rose to a long-haired Megadeth member, saying sweetly, "A rose for the lady?" It was thrown back in his face.

Wearing a Justin Bieber-esque wig, he was asked by Nicki Minaj, "Do you see how crazy you look?" This, coming from a woman with her hair fashioned after an animal print and topped by a beehive reminiscent of Bride of Frankenstein. He replied, "No. Do you see how crazy you look?" She burst out laughing.

The real Justin Bieber then passed by. Guillermo said, "Wow, he smell like cookies!" Marc Anthony roughed him up a little for giving Jennifer Lopez a rose, and Guillermo had just one question for Jamie Foxx: "How do you make babies?"
