When Conan O'Brien stops by your show, it's a big deal. When he stops by your show and he's naked...well, that's a really big deal.
The late-night host made an appearance on last night's special 1,081st episode of Chelsea Lately, participating in a hilarious shower scene with Chelsea Handler. In the sketch, Conan accused Chelsea of "stealing" his studio, did a little anger management, and got a black eye in a very unexpected way.
The hour-long special also featured appearances from Josh Duhamel and frequent Chelsea Lately guest Blake Shelton. Duhamel opened up about his excitement at becoming a father, and even dressed up in a tuxedo for the occasion.
Shelton and Handler wasted no time in getting into their usual banter: Chelsea broke Shelton's album display, and Shelton boasted about his success with women in college (using more colorful terms).
But at the end of the show, Shelton performed his new single "Sure Be Cool If You Did" and Handler had to admit: "I finally found you sexy!"
Tune in for new episodes of Chelsea Lately weeknights at 11/10c, only on E!
