Once again, Rob Kardashian has crossed the line!
The 29-year-old revealed in a video interview that his childhood crush was older sister Kim Kardashian (Ew, ew, ew!!)
After the reality star declared that Blac Chyna had a thing for Latin singer Ricky Martin, his bride-to-be revealed that his former crushes included Jennifer Lopez and his 35-year-old sibling.
"That is also pretty accurate…" Rob responded, blushing.
Needless to say, fans were a little wigged out by the confession. Rob and Chyna are currently expecting their first child, a girl, together.
