“Butt implants are the new thing, so Kim Kardashian, watch out,” Heidi Montag bellowed during her Heidiwood Clothing Line Fashion Show in Los Angeles last weekend. The Hills star wasn’t kidding when she lamented to friends that she wanted a “Jessica Biel Booty” several monts back. In late March, twenty-one year Heidi old made a top secret visit to Dr. 90210 Garth Fisher to inquire about getting butt implants. “She has no butt,” a friend of the MTV reality star tells In Touch Weekly. “She doesn’t want to have plastic surgery, but she may have no choice…She’s still insecure about her body….She doesn’t want to be as big as Jennifer Lopez, but she does want a little more booty.”
