After initially scoffing at her dad’s choice of title for his third child, Alabama, 17, has now asserted Rocky 13 is a “cool” name for her half-brother. “We all have very authentic, weird names. I love Rocky, I do. Definitely like Rocky.” Alabama’s 20-year-old brother’s name is Landon, while her step siblings – Kourtney Kardashian’s three kids – are named Mason, 13, Penelope, 11, and Reign, eight. Alabama teased Travis after the Blink-182 drummer first announced the name during a joint interview with Complex.
