(Cover) - EN Showbiz - Kelly Osbourne insists she has the world's most embarrassing parents.

The 26-year-old reality television star is the daughter of Sharon and Ozzy Osbourne.

Sharon recently revealed that her rock star husband has mastered the art of texting, and the pair have since enjoyed exchanging steamy messages.

Kelly has admitted she was mortified by the revelation.

"When it comes to embarrassing mothers, mine wins hands down. Mum recently decided to tell the world how my dad has finally entered the 21st century and learnt how to text and now they've discovered sexting!" she explained in Closer magazine.

However, Kelly says that her parents' new romantic plans may be foiled. The outspoken blonde has joked that both her mom and dad struggle when it comes to spelling, so their messages would become lost in translation.

"Well, if this is true, I doubt very much that any of it would make sense because neither one of them can spell to save their lives," she quipped.

Sharon has previously revealed that husband Ozzy is far more romantic than she is. Despite his rock star exterior, Sharon insists he is a "softie" at heart.

"I'm kind of straight to it, cut and dried, and he's not," she previously explained. "He's always been like that, he's a real softie." (C) Cover Media
