Selena Gomez had quite the eventful Monday night at the Grammys, where she introduced performers Ellie Goulding and Andra Day. On the red carpet, the Revival singer wowed the crowd by standing up for single people everywhere and flaunting a gorgeous blue Calvin Klein gown. Her over-the-shoulder come-hither glance is enough to make anybody swoon.

"I'm very happy because I wanted to feel like a blue sapphire rock/sparkly ball," Gomez, laughing, told Entertainment Tonight about the look. "I don't even know what I wanted to feel like, I just love it."

When asked about ex Justin Bieber, who won his first Grammy earlier in the night for "Where Are Ü Now," his collab with Jack Ü, Gomez kept her response short and sweet: "[I'm] very happy for him. I know. Honestly, [it's] so cool."

"They have such a cool energy amongst all of them to be able to create something like that. It's actually really great," she continued.
