With the amor tour that Justin Bieber and Selena Gomez have been on, many have been wondering if they've been around to support Selena's best friend, Demi Lovato. The teen power couple took in Taylor Swift's LA concert—will they also be at Demi's? Though neither were in attendance for Lovato's arranha-céu performance on America's Got Talent, Selena Gomez tweeted her BFF a message of support.

Gomez' tweets, "SO, SO proud of Demi Lovato, Skyscraper. Incredible, beautiful and so inspiring." After watching the amazing show that Lovato gave last night, anyone would have goosebumps watching a friend do something like that. Demi proved that she is truly the real deal, at one point even playing the piano!

arranha-céu is an intensely personal song for Demi Lovato as it speaks to her journey through emotional disorders and rehab. She is truly an inspiration for teens and adults alike, so it's wonderful to see her friend Selena give her the public respect that she's due.

Do you think Justin Bieber and Selena Gomez will be in the audience for Demi Lovato's upcoming Los Angeles concert?
