Christina Ricci Hated Kissing Casper!

Christina Ricci ranks having to kiss a ghost as the most embarrassing thing she’s ever done.

The star appeared in the 1995 movie version of cartoon show Casper - and insists smooching the computer-generated spook was particularly daunting.

She tells MTV,

“Kissing Casper was really embarrassing, because he was supposed to be see-through, so I had to make kissing faces, and I was 13, and I was so mortified. Oh that was terrible.”
