Nicole Richie's rocking daughter

Nicole Richie and Joel Madden took baby daughter Harlow to the Coachella Valley Music and Arts Festival this weekend.

The Good Charlotte rocker decided his fiancee needed a well-earned break after becoming a mother in January, and thought the famous music event would be perfect.

He said: "Nicole hasn't been able to do a whole lot over the year, so we're having a little family trip. I rented a house and surprised Nicole with a weekend trip because she likes Coachella.

"She was like, 'I really want to go!' So I surprised her. We brought the baby too. We love just hanging by the pool."

The 29-year-old musician - who also played a DJ set at a pre-festival party on Saturday (26.04.08) - also spoke about rumours Nicole's best friend Paris Hilton is planning to tie the knot to his twin brother Benji.

When asked who he thought would marry first, he replied: "We're the family with the baby so I think probably us, but who knows!"

Other celebrities at the Coachella festival included Sean Penn - who encouraged young people to get more involved in political and environmental issues - Kelly Osbourne and Dita Von Teese.

The famous event was headlined on Saturday by Prince, who treated fans to a set of his greatest hits including 'Purple Rain'.

He also surprisingly performed a cover of the Radiohead classic 'Creep'.
