Noah Cyrus has epic 20th birthday party with Tana Mongeau, actress Bella Thorne, and Machine Gun Kelly at The Roxy Theater in West Hollywood.

The singer was hands-on with her birthday cake featuring a photo of herself and Ritz crackers as she took a big handful while YouTube sensation Tana Mongeau watched and filmed the scene.



She was joined by Machine Gun Kelly as they posed flipping the bird during her party.

The young starlet was pictured as she walked around her birthday bash passing out pepperoni pizza as the party was well underway.



Tana was spotted as she held the singer’s hair up (what are friends for!) wearing a graphic cropped top showing off underboob, black lace-up bottoms, and black knee high boots.

Cyrus was the center of attention as her famous friends gathered in spite of their past relationship woes with Bella Thorne making out with boyfriend Benjamin Mascolo as ex-boyfriend Mod Sun stood in the same room —if you recall, Tana Mongenau (who is rumored to be now dating Noah) also had a tumultuous  relationship with the former Disney actress before she started dating Mod Sun— talk about a mind bender.
