Rob Kardashian once had a crush on his sister Kim Kardashian West.
The 29-year-old reality TV star, who is expecting his first child with fiancée Blac Chyna, dropped the bombshell during an interview with E!
The couple were asked to reveal their first crushes, to which Rob replied: "Her childhood crush is Ricky Martin"
But Chyna wasn't embarrassed by his revelation, in fact she started giggling and singing his 1999 hit Livin' La Vida Loca.
But it wasn't long before she sought to get her own back on her other half.
