Actress Charlize Theron stepped down from the stage at a party premiere and kissed Shirley MacLaine's bottom, in an attempt to pay her respects to the lady.

Theron, invited to the Premiere Icon party on Tuesday night, thought it would be a good idea to pay her tribute to the great actress Shirley MacLaine, but in a strange way. Charlize stepped down from the stage, went straight to MacLaine and kissed her on the bottom.

Later, a red-face Theron blamed her show-stopping tribute on the pills she was taking for an aching neck.

As she said, "it was a combination of my painkillers and the fact that everybody was paying tribute to this incredible woman, this incredible actress, so I had to go to the physical aspect of kissing her a**."

Theron, who has received a prize that night at the Hollywood bash, admitted she has been amused with her heroine's response: "She loved it. She said it was the best she's had all year."

MacLaine was also thrilled about what happened, stating after the incident that she wants to hang out with Theron to know her better. "I've gotta get to know her... I should get drunk with her."
