At Chicago’s sold out show Saturday night (June 10) at the Los Angeles Forum, Amber Rose brought her son, Sebastian, backstage to meet Chicago and sing with them on a number of big hits, including “Saturday In The Park,” with Robert Lamm, who will be inducted into the Songwriters Hall Of Fame on June 15 along with band member Jimmy Pankow.

Sebastian also sang several other hits with the entire band in the dressing room including “You're The Inspiration” and “Hard To Say I'm Sorry.”  He knew all the words.

The band invited him to come back the next time they play in LA and come on stage for a song. Wiz Khalifa is his Dad, so music is in his blood.

Amber Rose posted several Chicago videos to her social media accounts and the one featuring her son Sebastian singing in the crowd has received nearly one million views as of the next morning.
