This got really weird, really fast.

While Rob Kardashian and Blac Chyna discuss childhood crushes in a preview clip for an episode of their new reality show, Rob & Chyna, the 29-year-old Kardashian brother sort of admits to having crushed on Kim Kardashian West.... his sister.

"Her childhood crush is Ricky Martin," Rob shares of Chyna, who agrees by doing a little dance and belting out the singer's famous lyric, "Livin' la vida loca!"
