London, Sep 11 (Inditop.com) 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.
