26 February 2010America's Next Top Model winner Yoanna House has spoken out about her cosmetic surgery, saying that only her breasts have been enhanced. According to E! Online, the discussion came after Yoanna's appearance at the CW: It's a Reality party in New York City, which led many bloggers to speculate that the 29-year-old model had undergone plastic surgery to her face since her appearance on the hit show.Yoanna said that she had not had any work done to her face, and admitted that other factors may have caused her appearance to change over the past six years. "I know that I've changed," Yoanna said. "I just had a baby about a year ago, and I put on a lot of weight ... My baby doesn't sleep through the night, so that might age you a little bit. Other than that, I've never done anything to my face, besides going a little too overboard with bronzer." She also said that she currently has no plans to change her face, explaining: "I'm just going to stick with my bronzer and my great makeup artist who contours me." The only cosmetic surgery procedure Yoanna has undergone is a boob job, to achieve a bust size she was happy with. "I did enhance my breasts," Yoanna revealed. "That was a personal decision I decided to make a couple of years ago. I wasn't happy with the way I looked. I thought I had a boyish figure. I wanted to look more womanly, and I think it's the best decision I've ever made."
