Mrs O overwhelmed with pride

Kelly Osbourne made her West End stage debut in the musical Chicago last night and had her mother in tears.

Kelly, 22, started her 7-week run in the show in front of a celebrity-packed audience that included Kate Moss and Amy Winehouse.

Her performance went down a storm and her mum, Sharon, 54, was visibly overcome with pride and nerves as she arrived at the Cambridge Theatre.

‘She was just a bit overwhelmed, that’s her little girl up on stage,’ fellow X Factor judge Louis Walsh tells The Sun.

Kelly is the youngest actress to play the role of Mama Morton in the hit production.
