Singer Mariah Carey was left drenched in urine after her beloved dog Cha Cha relieved himself on her just before she was due to perform live.
The 40-year-old singer, who is due to perform in Las Vegas on Friday and Saturday, wrote on her Twitter page: "OK so Cha Cha just peed on the floor in my dressing room and then decided to jump on top of me as I am doing my make-up. 'Real classy' here."
It is believed she was practising for her upcoming shows when the toilet trouble occurred. Her husband Nick Cannon gave her the mutt to celebrate their one-year wedding anniversary in May.
But Carey is not the first celebrity to suffer the embarrassment of an animal urinating on her. Katy Perry was mortified when a monkey peed on her during a magazine shoot.
