Will Lady Gaga be the next Heidi Montag?

Getty ImagesLady Gaga has always marched to her own beat when it comes to her style and appearance, but lately her body seems to be shrinking. Her trainer and the author of 5-Factor World Diet, Harley Pasternak says her dedication to getting fit is ruthless. "Lady Gaga has always been active, but about a year ago, she decided she wanted to have the best abs, legs and arms ever, so she stepped up her workouts," he told In Touch. Gaga now works out 4 to 5 days a week in addition to her regular tour schedule. "Like most stars, she doesn't have a ton of time, so when she is with me she stays focused and never complains, no matter how hard I push her," says Pasternak. "Now she is super-confident about her body and comfortable wearing everything and anything."

Or is she? Friends close to the 24-year-old star say Lady Gaga is still totally unsatisfied with her appearance. "She's running on empty and not taking proper care of herself at all," one insider told Hollyscoop. "She's desperately unhappy but keeps talking about having thousands of dollars worth of plastic surgery. She really thinks that could fix everything." Noooo! One thing we have always liked about Gaga was that she was unique and didn't buy into the traditional cookie cutter popstar look. The insider said, "she's completely preoccupied with overhauling her looks," and that she's got a grocery list of body parts she wants to change, not unlike Heidi Montag's recent cosmetic overhaul. At the top of Gaga's list: a nose job, cheek implants, a boob job, and thigh and butt lift.

Please tell us this isn't true! Heidi Montag's shocking before and after photos are so horrifying that we don't know how anyone will be able to take her seriously anymore. Um, not that they really could before. Lady Gaga may not look human in some of her costumes, but that doesn't mean she should be made of plastic. Gaga, if you're listening, don't do it!
