Listen to Ariana Grande on iHeartRadio

Ariana Grande wowed the crowd with her incredible pipes at 106.1 KISS FM's Jingle Ball in Dallas, Texas Monday night, where she revealed to the audience that she was extremely nervous because it's the first time she has every performed at a Jingle Ball concert! Awww!

But luckily for Ariana, she had some major support: her boyfriend, The Wanted's Nathan Sykes was there with her! She must love The Way he supports her.

After her incredible performance, Ariana and Nathan stopped backstage to chat with Jason Derulo!

Hmmm, that reminds us of another member of The Wanted who got support from a significant other at a Jingle Ball concert this time last year! Remember when Lindsay Lohan showed up at Q102 Philly's Jingle Ball?

Moving on...

On the red carpet, Ariana told reporters that her favorite holiday movie is The Nightmare Before Christmas because she loves scary flicks! She even revealed that she likes Halloween more than Christmas. Maybe next year she'll release some spooky songs in honor of her favorite holiday!

Ariana also admitted she changed up her hair to shut up the haters on Instagram and social media who complain she never changes her look. She says she identifies with girls in school who also get social media hate and says not to take it too seriously.

Ariana said the craziest thing ever thrown on stage during one of her performances was a bra, but was totally creeped out by a fan who mailed her clothes -- that were his dead wife's!
