Wiz Khalifa and soon-to-be ex-wife Amber Rose reunited for son Sebastian this week.

The 27-year-old rapper had a friendly run-in with the 31-year-old model at his Boys of Zummer concert with Fall Out Boy at Hollywood Bowl in Los Angeles. Rose brought their two-year-old son along to see his dad perform.

"Our Lil Rockstar! Sebastian took over his Dad's show last night," the model captioned a video of Sebastian joining Khalifa onstage. She also shared a photo of herself with the toddler at the concert, writing, "My Greatest Gift."

The former couple even posed together for a picture with Veronica Mars and Party Down star Ryan Hansen. The actor posted the snapshot on Instagram, joking, "Proud to announce my new gig as Divorce Counselor for @mistercap and @amberrose."
