Heidi Montag has been blasted by actress Emmy Rossum for boasting about having ten cosmetic surgery procedures in one day.

The reality TV star, who is married to Spencer Pratt, was videoed sitting on a hospital bed in a gown saying that she was having plastic surgery to help her "feel comfortable as a woman".

The Phantom of the Opera star Rossum later wrote on her Twitter page: "It upsets me to see young women in the spotlight advocating plastic surgery.

"ANY surgery is extremely dangerous and should not be taken lightly, much less, used as a tool to increase notoriety or popularity.

"By putting this on magazine covers, we are somehow legitimising the dangerous lengths to which some will go for fame and beauty.

"There are so many REAL ISSUES in this world that NEED attention. Let's try to take a moment to be grateful we are ALIVE."
