Kelly Osbourne has whisked her mum Sharon to Las Vegas to celebrate America's Mother's Day on Sunday - and has vowed to donate any money she wins from gambling to charity.
Kelly Osbourne and her mum Sharon Osbourne have always been close, and they jetted off to Sin City on Thursday to spend a girly weekend together.
In a post on her Twitter page, Kelly writes, "On the way to vegas with my Mumma... to spend Mothers day with her. I have the best mum in the world."
Updating her fans once they'd settled in, Kelly declared she'd already won cash on the slot machines - and, after using the money to buy a gift for Sharon, planned to give all her other winnings to her mother's charity, the Sharon Osbourne Colon Cancer Program.
Kelly adds, "Just won $120 on a 1 cent slot machine! I never win anything. The money I won is going towards my mums mothers day gift! But if I win any more money from the slots it's all going to my mum's colon cancer charity! On my way back down to test my luck!"
