Sharon Osbourne left her son Jack red-faced when she flashed her surgically enhanced breasts to his friends. Sharon was so pleased with the results of her boob job - which boosted her bust size to a massive 34DD in July 2005 - she couldn't resist showing off her new charms to her son's pals. Jack said: "Mom came in and asked my friends if they liked her new tits, before she lifted up her shirt and flashed to my two best friends." Jack - who stars in his own reality TV show 'Adrenaline Junkie' - has also revealed he is glad to have finally kicked his drug and alcohol habits after two stints in rehab. He said: "My life is now totally different and most important thing is my family. "Jack, 21, shot to fame at the early age of 14 when he starred in the MTV fly-on-the-wall show 'The Osbournes' with mother Sharon, father Ozzy and sister Kelly.
