Even the most diehard Teen Mom fan could be forgiven for failing to recognize Farrah Abraham these days.
The 21-year-old MTV star -- who underwent a $16,000 nose job and chin implant last month -- looked like a completely different person when she donned a long, platinum blonde wig during a Los Angeles shopping trip Saturday, Nov. 17.

Abraham didn't sport the hairpiece when she stopped by Us Weekly's post-American Music Awards party in L.A. Sunday, Nov. 18, although she did open up to Us about why she decided to alter her face. (This wasn't the first time Abraham has gone under the knife for cosmetic reasons; in 2011, the mom to Sophia, 3, paid $5,000 for a breast augmentation going from an A to a C cup.)
"I waited a lot of years and I dealt with a lot of criticism about certain things on my face, and once I turned 21 I still felt that I wanted to change that, so I did," the Iowa native explained. "I'm done with thinking about [it] and I don't have to think about my face. I just put makeup on, or not, and I go."

Abraham emphasized that it wasn't anything self-esteem related that convinced her to make such dramatic changes. "I've always been confident," she shared. "[People's comments were] just something that annoyed me."
So how have other folks -- and her loved ones, in particular -- reacted to her new look?

"My friends and family don't care," she told Us, explaining that they haven't really had many conversations about it at all. "I don't like to talk about my looks. I'm just like 'Hi, bye.' I don't really care."
