Kylie Jenner and Tyga just couldn't help but show sweet PDA during their outing in New York City on Tuesday. The on-again, off-again couple cuddled up while taking a walk after attending Kanye West [1]'s concert with other members of Kylie's family. Kylie, who looked casual in a black t-shirt and Vans, also showed off her new bleach-blond hair [2]. Not only did the rapper keep his arms locked tight around his girlfriend's waist, but he even snuck a few side kisses as they walked. After briefly splitting earlier this year [3], it seems these two are back to being young and in love [4].
