Tinseltown’s latest young power couple? According to Us Weekly, it’s Jaden Smith and Kylie Jenner. The 14-year-old Karate Kid actor (and son of Will and Jada) and the 15-year-old reality starlet (and Kardashian clan member) were reportedly spotted out on a date in London over the weekend, where Smith was in town to help celebrate his pal Justin Bieber’s birthday. (Spoiler: The party didn’t go so well.)
