Selena Gomez makes her comeback in a corset at American Music Awards in her first live performance int two years

Selena Gomez made her eagerly awaited comeback with a performance of new music at the American Music Awards on Sunday night, her first live TV performance in two years. 

While the nerves showed at times, the 27-year-old opened the show with passion, performing an intense choreographed dance routine while singing her new songs Lose You to Love Me and Look at Her Now. 

Just days after revealing body shaming 'messed me up,' Selena had a daring onstage costume change, switching her black dress for a tight sparkling corset, the Daily Mail reports.  

Her celebrity pals lapped up the show, with Selena's longterm BFF Taylor Swift and new bestie Halsey dancing along and singing to her performance.

Earlier in the evening Selena looked confident and radiant on the red carpet.

The singer hit the red carpet at the Microsoft Theater in downtown Los Angeles, graciously posing for selfies with fans who were waiting to see their favorite stars.

Gomez was wearing a neon lime green mini-dress, with a pair of matching neon lime green pumps.

She wore her hair down in a bob style, with a layered diamond choker around her neck.

After her performance Gomez took to Instagram to share a collage of behind-the-scenes photos from the AMAs, including one that revealed a new thigh tattoo.

While the new ink wasn't visible on the red carpet, it was seen partially peeking out from under her one-piece outfit when she changed costumes on stage.

The tattoo featured a pair of hands praying with a rosary wrapped around them, with Gomez tagging the New York City tattoo shop Bang Bang Tattoo in her post.

Her appearance came days after her appearance on the Giving Back Generation podcast, where she talked of being body-shamed.

Gomez was diagnosed with lupus in 2015, with the singer and actress revealing that she now deals with, 'a lot of health issues, and for me that's when I really started noticing more of the body image stuff.'

She added that the medication she has to take for the rest of her life was one factor that lead to her weight fluctuations, stating: “It depends on even the month, to be honest.”
