So Rob IS the man of the Kardashian house?!

Only two days after Blac Chyna got into a catfight with social media maven Alexis Skyy, her ex, Rob Kardashian, decided it was time to shoot his shot.

After Alexis posted a sexy flick on Instagram, Rob admitted he’s been crushing on her.

Last week, the two women got in a fight at a private party in Los Angeles. Alexis, who has appeared on Love & Hip Hop, claimed that Rob’s ex threw a drink at her.
