Christina Ricci and Owen Benjamin have called off their engagement. The "Speed Racer" actress agreed to marry to comedian Owen in March this year but the couple decided to end their wedding plans earlier this week after a huge argument.

A source told People magazine: "Owen had a birthday party this past Sunday, and everything seemed fine. Sometime after, they got into a fight and decided to re-evaluate things. Then the engagement was off."

Katy Perry was mortified when a chimpanzee urinated on her. The "I Kissed A Girl" singer was posing for a magazine shoot, when the lively animal - which was on the set for the photo shoot - relieved itself on her.

She wrote on her blog: "Jeremy Scott is one of my all time favorites and he shot the pictures while I got to prance around in his creations. I had a chimp on set with me that day. Fun fact, she peed all over me, I had to take a silkwood shower in the middle of shooting."
