There are certain things parents simply don't do in front of their kids' friends - exposing your half-naked body is one of them. But Sharon Osbourne is the last person who would listen.
Sharon recently left her son Jack totally embarrassed when she flashed her surgically enhanced breasts to his friends - although we're sure they weren't complaining.
Sharon was so pleased with the results of her boob job - which boosted her bust size to a 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 t**s, 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."
The 21-year-old 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.
