Wiz Khalifa and Amber Rose's son Sebastian (or "Bash" for short) is already five years old. To celebrate his birthday, Khalifa and Rose threw him a Suicide Squad-themed party at Dave & Buster's—complete with costumes of their favorite characters from the 2016 DC Comics film.

Rose dressed up as Harley Quinn, while Khalifa and his son rocked green hair and face paint as they each transformed into the Joker.

After Khalifa and Rose split in 2014 following a brief marriage, they have remained friendly with each other as they continue to raise Sebastian together. In early 2017, Rose told fans, "I’m super sad and I would like to let my supporters know what’s going on in my life. Wiz and I are family and we will be family for the rest of our lives for Sebastian."

This weekend, they were all smiles as both Khalifa and Rose excitedly posted photos and videos from the celebration. Sharing a picture of Sebastian singing along to Michael Jackson’s "Man in the Mirror" and Queen’s "Bohemian Rhapsody," Khalifa wrote, "Ba$h had the best birthday party yesterday. Everyone left turnt and we even got a special performance."

Rose also shared a sweet message for her son in an Instagram caption that read, "Happy Birthday to my handsome, sweet, smart, sensitive, compassionate son #sebastiantaylorthomaz. I can’t believe he’s five years old already."
