Sandra Bullock outside of the Comedy Central studios for 'The Daily Show with John Stewart'. New York City, USA - 15.03.07

The actress became hooked on the show while co-starring with Nip/Tuck actor JULIAN McMAHON in movie PREMONITION.

And she's begging McMahon to help her land a guest spot.

Bullock, 42, says, "I love Nip/Tick. I've told Julian I'd like to be a guest on the last ever one and have a complete overhaul starting with these (my breasts). It'd be fun."
