On The Hills' sixth season premiere Tuesday, Heidi Montag's family grills her about undergoing 10 plastic surgery operations in one day.
Her sister Holly tells her she was shocked Heidi, 23, got all the work done because she always had "confidence ... I don't know what happened" (see clip, above).
Heidi, 23, says she just "wanted to be happier."
But her mom tells Heidi she needs to deal with her "insecurity on a psychological level."
"You don't live where I live!" Heidi snaps back.
"So should you not live in that area?" her mom asks her.
The extent of Heidi's surgery is revealed when the reality star tries to eat a burger.
"How's that burger?" her sister asks.
"I can't really chew it," Heidi says.
Flustered, her mom spats, "Want me to put it in a blender for you?"
Check out the full episode of The Hills Tuesday at 10 p.m./ET on MTV.
