She doesn't look quite like herself.

Lady Gaga belted out her new tunes on X-Factor UK Sunday night, but fans and viewers had more to say about her changed appearance than her performance. "How is that Lady Gaga? She has a completely different face! Who is this imposter?" one Twitter user wrote.

We have to admit that we see what they're talking about! While we think she looks gorgeous, we have a feeling she got a nose job and some serious Botox.

In other more important Mother Monster news, the singer just confessed during a Today show segment this morning that she suffers from mental illness after being raped at age 19. "I suffer from PTSD. I've never told anyone that before, so here we are," she told a group of LGBT youth while visiting New York City's Ali Forney Center.

"The kindness that's shown to me by doctors as well as my family and my friends, it’s really saved my life. Kindness, to me, is an action of love or a showing of love to someone else. I also believe that kindness is the cure to violence and hatred around the world. I like to share kindness in a lot of different ways," she added while promoting the #ShareKindness campaign.

Maybe people should focus less on her looks and more on her kind heart. Just a thought!
