Selena's mystery man is an old friend named Alfredo Flores

Calm down, everyone, Selena Gomez is still single. After appearing at the Warner Music Group/InStyle Grammy after party with a new guy on her arm, many seemed to think Selena had moved on from Justin Bieber. 

Not quite the case, according to E! Online. The young man with Selena at the party was actually an old friend, Alfredo Flores. The two have known each other since before she dated Bieber, and they're just friends.

Selena attended the party after dancing the night away at Justin Tumberlake's show at the Hollywood Palladium, tweeting, "He's bringing sexy back... And it's about time!" Included with the tweet was a photo of her dancing with a female friend.

Bieber, on the other hand, wasn't at any Grammy-related events. After not being nominated, he stayed home to pout, while trying to get his live video stream to work. It didn't. It's alright, though, Bieber has his new feud with the Black Keys' drummer Patrick Carney to keep him busy.
