No More Plastic Surgery, Says Ashley Tisdale

High School Musical star Ashley Tisdale is finding herself on the defensive again after rumors surfaced last week that she got more plastic surgery.

Ashley scoffs at the idea and says she's no Heidi Montag.

"People are saying I had another nose job. I did not. That's ridiculous," Tisdale said. "I was away in New Zealand filming a movie (They Came From Upstairs) and people think I went away to have more work done. I didn't."

Tisdale had a nose job in last November to correct a "deviated septum" and to "smooth out two bumps" from when she "fractured her nose" as a "teen."

The singer and actress was ripped by some critics, saying that she didn't have to change the entire look of her nose in order to fix her septum.

"[Celebrity gossip] tabloids have doctors talk about what they think I did with my surgery, but they did not examine me," Ashley Tisdale responded.

"They don't know what I have inside my nose."

"It's very irresponsible for a medical professional to comment on someone whom they have not examined," adds Tisdale's rep, Scott Appel.

Rumors also recently surfaced that Tisdale, who is in Utah to film High School Musical 3, recently had a breast augmentation.

"Look at me," the 22-year-old blonde said, laughing at the boob job rumor.

"Does it look like it to you? No! It's ridiculous. I'm not for plastic surgery... I'm not going to get another surgery. I can promise you that."

Hope you like her the way she is, Jared Murillo.
