Rod Stewart's daughter plays CMC Rocks

Ruby Stewart will step out of her famous father's shadow and play at her first music festival at CMC Rocks in Queensland.

The daughter of Rod Stewart and former Sports Illustrated model Kelly Emberg, whom he dated in the eighties, plays in The Sisterhood with her bestie Alyssa Bonagura, appearing at Sunday's festival in Ipswich.

They formed about a year ago after Rod heard them singing together when they travelled on a private jet.

The 28-year-old said being the daughter of one of the greatest-selling artists of all time has not been a tough cross to bear.

"My dad is so supportive and he's a great dad, so maybe that's why it's always never felt like a weird thing for me," Ruby told AAP.

"He gave us the idea (to form). We were on a plane together, as I had just performed with my dad in Vegas, and we were on the way back and playing some Joni Mitchell songs and playing some harmonies and my dad said 'you two should start a band, your voices are good together'."

The pair regularly ask Rod for advice about their music and they even play a cover version of his 1970 song Gasoline Alley, from the album with the same name.

Ruby, Bonagura and Emberg, who has made the trip with her daughter to Australia, have been staying at Aussie country music star Morgan Evans' Newcastle home.

They are also using Evans' band for their Sunday afternoon appearance on the main stage.

"It's the first time we have played for an hour, so we are super excited and nervous," Ruby said.

Her bandmate is also from a musical family background, the daughter of Michael Bonagura and Kathie Baillie, who played in country music band Baillie & the Boys, which had a string of hits in the US in the eighties.

"I grew up on a bus, and she grew up on a private jet, listening to music. So it's all the same," Bonagura said with a laugh.
