Penelope Disick spent her 9th birthday rocking out on her new drum set with mom’s boyfriend Travis Barker

A sweet post from Kourtney Kardashian showed the child sitting at her light-pink drum set while the Blink 182 drummer assisted with the hi-hat. 

Scott Disick also paid tribute to his daughter on Instagram, writing, “I love you to much!!!!!! And will never stop loving you each and every day for the rest of your life and will protect you till the day I die.”
