Rod Stewart has eight kids, and at least one of them is following in the old man's footsteps. A Diet Pepsi commercial that premiered during Sunday night's Golden Globes Awards features Modern Family star Sofia Vergara dancing to a version of the Damn Yankees song "Whatever Lola Wants," sung by Rod's daughter Ruby Stewart.

Ruby's mom is model Kelly Emberg...she and Rod dated from 1983 to 1990, but never married.

Twenty-four-year-old Ruby has joined her father onstage during his concerts to belt out renditions of oldies like "Son of a Preacher Man" and "Rescue Me," to good reviews.
