Justin Bieber quieted any relationship rumors for the night when he walked the Grammys red carpet with his little brother Jaxon on Monday evening. The little Bieber wore a black tuxedo while his older brother donned a white suit jacket over his all-black ensemble.

Jaxon played it cool on the red carpet, keeping a straight face and his arms crossed even when Justin laid a big smooch on his cheek in front of all the photographers. The little guy also got an assist on his tie by Grammys host LL Cool J.

Justin's good night continued when he took home his first Grammy award for his song "Where Are Ü Now" with Skrillex and Diplo. The trio gave an electrifying performance of the song during the ceremony following Bieber's stripped-down rendition of "Love Yourself."

The Grammy win also granted Bieber's wish from 2010 when he tweeted on New Year's Eve that his dream for 2011 "would be to win a grammy. that would be a amazing." Five years later that dream came true, and his ex-girlfriend Selena Gomez made sure to pass along her congratulations to Justin and his collaborators.

"I'm very happy for him. Honestly, so cool," Gomez told Entertainment Tonight. "They have such a cool energy amongst all of them to be able to create something like that. It's really great."

Bieber and Gomez will both hit the road this summer for separate tours. Gomez kicks of her Revival Tour in Las Vegas on May 6. Bieber's Purpose World Tour starts in Seattle on March 9.
