According to Instagram proof, Justin brought on his big day with his hot "friends" and once rumored girlfriends, Yovanna Venutra and Hailey Baldwin. It was obvious Selena wasn't there because not only weren't there any photos of the two of them, but because she posted a picture on Instagram that day with another dude. Ouch.
Her pic wasn't with her rumored boo Zedd, but with Justin's good friend Cody Simpson. They apparently hung out and went out to dinner together.
It's pretty surprising that Cody didn't go to Bieber's party. Not only are they buddies, but they just released a co-album together.
So what could this mean? Why would Cody miss JB's big party? Why would he post pics with his ex? Hmmm. Makes you wonder if a beef went down, right?
