Kelly Osbourne — known as much for her acid tongue as she is for her outspoken nature — has a bit of a soft spot for The Hills’ villainess Heidi Montag. The 25-year-old is saddened that the reality personality is “obviously insecure” about her appearance.

Earlier this month, a barely-recognizable Heidi revealed that she underwent ten plastic surgery operations in one day back in November.

“She was so pretty before, and now she looks like a Barbie doll – I feel sorry for Heidi, she’s obviously insecure,” Osbourne wrote in an essay for Britain’s Closer Magazine.

Kellz, on the other hand, does have some strong words for Heidi’s plastic surgeon.

“It’s the surgeon who should be ashamed – he should be struck off for giving her so much work when she clearly didn’t need it.”
