These two lovebirds are SO back on!

Following the American Music Awards, Justin Bieber and Selena Gomez arrived at Bootsy Bellows in Hollywood .... walking in hand in hand.

We're told the twosome arrived at the 21+ nightclub just after 1:30am and stayed for about an hour.

Biebs, 18, and Selena, 20, then went back to her house. At that point, Ms. Gomez had taken off her shoes and was seen walking in barefoot.

Home sweet home with her AMA-winning beau.
