My, how times flies. Wiz Khalifa and Amber Rose's son, Sebastian is already 5 years old. The couple recently celebrated Lil Wiz's birthday with a costume party.

The Pittsburgh rapper shared some footage from the special day on his Instagram page yesterday (Feb. 24). In one video, Wiz, Amber, Bassy and a van full of family and friends travel to the shindig. Everyone is decked out in a costume. Wiz has his face painted up like the Joker and Sebastian is painted up just like his proud papa.

"We on the way to Bastian's birthday party and it's lit," Wiz says in the video.

Judging from the footage, the party was indeed lit. The venue was packed. King, Tyga and Blac Chyna's son, showed up to support his lil homie. The highlight of the whole party might have been Sebastian showing off his talents on the mic by singing some throwbacks, including Michael Jackson's "Man in the Mirror" and Queen's "Bohemian Rhapsody."

In related news, Sebastian recently got his hair dyed blond. "He begged me for a whole year to dye his hair blonde like mine so we started with a little patch and I told him when he turns 5 I will make him a full blonde like his mommy," Amber wrote in the caption of the reveal on Instagram. "He will be 5 on the 21st of February! He’s so happy and none of you dirty little trolls can take that away from him or me! 😍😍😍 P.S Love your children unconditionally and let them be creative this world will be a better place 🙏🏽❤️😘."
