Amber and her BF, Alexander "AE" Edwards, hit up Staples Center Friday night, where they took in a concert with the likes of Meek Mill, YG, A-Boogie Wit da Hoodie, and Blueface.

Amber announced on April 3 that she's pregnant, and she showed off the work in progress in spectacular fashion.

There's an interesting connection with AE. He's Tyga's best friend. As you know, Tyga and Blac Chyna had a kid together and Chyna is Amber's best friend.
