Kylie Jenner's appearance has changed a lot over the years, but has she had the help of a plastic surgeon? The "Keeping Up With the Kardashians" star recently opened up about plastic surgery rumors and whether or not momager Kris Jenner would allow her to undergo any nipping and tucking.

In an interview with Wonderland magazine (via E! Online), Kylie, 18, revealed that she has heard all the plastic surgery rumors. She copped to having gotten her lips done, adding that she "never lied" about the procedure, but rather withheld the truth. She went on to say that after coming clean about her lip injections, people decided that she must have had other work done. Kylie told the publication that anyone spreading those rumors fails to realize that she has only been legal for a few months and Kris, 60, simply wouldn't allow her to rush into making changes.

"People think that I've had everything done. I thought it was going to chill down when I said: 'OK, I admit it, I got my lips done, I never lied I just wasn't telling the whole truth,'" Kylie said. "And then people took that and were like, 'Oh, well, if she got her lips done she probably got everything done.' People don't realize I just turned 18, so there's no way my mom would ever let me undergo a nose job or a boob job."

While rumors about her ever-changing appearance continue to swirl, Kylie is focusing on her new business ventures. On Feb. 18 it was announced that Kylie would be teaming up with Puma as a brand ambassador. In a statement (via People) global director of brand and marketing Adam Petrick said he was "pleased and excited" to finally confirm that Kylie had signed on for their spring/summer women's training campaign. The announcement came just after brother-in-law Kanye West assured Twitter followers that Kylie would never cross him or his deal with Adidas. He later told TMZ he was initially annoyed by the deal, but had since cooled off enough to be "happy for her."

Despite working for a direct competitor of Adidas, Kylie has been there for Kanye every step of the way. She joined Kim, Kourtney and Khloé Kardashian, Lamar Odom, Kendall Jenner and Kris at New York City's Madison Square Garden on Feb. 11 to celebrate Yeezy Season 3. During the event the Kardashian-Jenner family was seen dancing along to songs from Kanye's latest album "The Life of Pablo."
