Blonde beauty JENNY McCARTHY showed off her charitable side on Thursday night (15SEP05), when she auctioned off a kiss to benefit victims of Hurricane Katrina.

The sexy pin-up, who filed for divorce from her husband JOHN ASNER last month (AUG05), made an appearance on comedian Jay Leno's chat show, where she unexpectedly announced that she'd happily lock lips with the highest bidder. She said, "I think, out of the goodness of my heart, I should auction off a kiss to somebody in the audience.... Girls included, by the way!"

The first bid of $100 (GBP55) was beaten out by a man who enthusiastically offered $500 (GBP277) for the privilege.

After Leno took the money from the excited audience member, McCarthy treated the man to a sexy, prolonged kiss - and even grabbed his buttocks as the audience cheered with delight.

McCarthy also got an equal amount of cash from Leno, who quipped, "I'm matching this and I'm not getting action, but never mind!"

The cash will go to the American Red Cross.
