Rob Kardashian put his now ex-girlfriend Rita Ora on blast last night on Twitter (his tweets have since been deleted) for supposedly cheating on him with over 20 GUYS! Check out his tweets below.

@RobKardashian: When a
woman cheats on you with one man I can live with that. People make mistakes,
trust me. I have forgiven numerous times...

@RobKardashian: But when a
woman disrespects herself by messing with more than 20 men all while being in a
relationship with a Faithful man...

@RobKardashian: I just don't get how a woman can do that to her body. And your
career hasn't even launched yet. I don't put up with sloppiness. LOYALTY.

@RobKardashian: This is a
lesson to all the young women out there to not have unprotected sex with
multiple men especially while in a relationship.

There are a lot of rumors about who the "guys" are she cheated on with.  One of the guys is supposedly a "high profile" artist who is friends with Kanye.  We've also heard that she's hooked up with Kanye (pre-Kim), as well as Kobe Bryant.  They weren't part of the 20.  Some of the 20 include:

Elijah Blake: Roc Nation label mate, who has been working in the studio on her Debut LP.

Evan Ross: Actor who meet Rita last year at a Roc Nation Party and through Rob Kardashian.

Meek Mill: Who is also signed to Roc Nation, and meet Rita at the Made in America festival.

Keithian: Pop Singer/Songwriter, and Sony label mate whose been working on her Debut LP.

Drake: Who we all know has written Rita's single R.I.P and wishes she was Rihanna.

Alex Pettyfer: British Actor who has always had a thing for Rita and has been seen lunching together.

Omar Grant: Who is Rita's A&R at Roc Nation and has been working closely on her project for years.
