The deejay took the stage to join his stepfather Mick Jones and his band Foreigner at her sister's Los Angeles fashion launch party.
Celebrity DJ Samantha Ronson showed off her singing skills on Tuesday night, May 4, when she joined stepfather Mick Jones and his band Foreigner onstage at sister Charlotte's Los Angeles fashion launch party.
The musical family all played a part in the JC Penney party entertainment, but Samantha's singing talents were the talk of the night. A partygoer tells WENN, "She was good. She knew all the words and had a very delicate voice... She was very excited to be onstage with the band and screamed, 'I'm singing with f**king Foreigner'."
It has not been mentioned the title of the song performed by the on-and-off girlfriend of Lindsay Lohan.
Paris Hilton and Mischa Barton were also among guests at the party, held at Hollywood's Milk Studios.
