Who knew???

Charlie Sheen had friends over (including roasters Jeffrey Ross and Jon Lovitz) to his house on Monday night to watch both the Two And A Half Men premiere and his Comedy Central Roast, and he basically live Tweeted the experience.

That's not all that surprising for Charlie, but we were shocked by who he Tweeted to!

Charlie Tweeted at Miley Cyrus, saying:

    "Thank you Miles!! Wish you were here tonight!! xo c RT @MileyCyrus #sheenroast HAHAHAHA"

"Miles"? Really? Why are these two on a nickname basis??

Miley, though, is a bit of a Charlie traitor. She Tweeted, "@aplusk on 2.5 men tonight! Hahaha so friggen funny! ;)"

UPDATE: In other Charlie news, the numbers are in, and his Comedy Central Roast was the highest-rated ever in the history of the franchise, with 6.4 million viewers. Of course, the premiere of Two And A Half Men got 27.7 million ... but was that only because viewers wanted to see how Charlie's character would be killed off? Stay tuned!
