1.Back when Selena and Demi were BFFs and caked on eyeshadow, they shared a YouTube vlog about their friendship and it was SOMETHING.

3.Speaking of Miley, she once rapped about why she deleted her Twitter in a video with stunning Windows Movie Maker transitions.
4.OH! And one time, Miley thanked Hilary Duff for "making it cool to be a good girl" after Hilary surprised her with a phone call. Lol, I'M DYING.

6....And she performed Christina Aguilera's "Ain't No Other Man" with her friend Misha. A star was born.
7.Beyoncé straight up fired Farrah Franklin from Destiny's Child on camera, a power move that left us with the iconic DC trio.
