Let's hope this chick doesn't use him like his baby mama did!

Rob Kardashian let it be known that he was crushing on Instagram model Alexis Skyy by calling her his #WCW on social media, and in a matter of hours, the reclusive reality star was cooking dinner with her in momager Kris Jenner's kitchen. He works quickly!

This new romance is bound to piss off his ex Blac Chyna, who coincidentally got into an altercation with Skyy at a nightclub over the weekend. The former stripper allegedly threw a drink at Rob's lady and demanded she get out of her VIP section, and now they're officially rivals.

Kimmy K's little bro is already feeling defensive over the relationship, too!

"Rob Kardashian never learns! Leave the pettiness to the ladies. Alexis just doing all this to spite Chyna! Grow tf up Rob," one Twitter user wrote, and he immediately fired back. "Me and Alexis known each other for 5 years so stop with that," he responded.

He doesn't have the greatest track record with women, so we hope this works out!
