Joel Madden: 'Nicole is supermom'

Joel Madden has revealed that he believes his partner Nicole Richie makes a good parent.

The Good Charlotte frontman and Richie have two children together, Harlow, 2, and 9-month old Sparrow.

Speaking to People, he said: "She's supermom."

Madden also admitted that motherhood hasn't taken away Richie's mischievous side, saying: "Nicole always hacks my Twitter and writes the weirdest things. It's embarrassing, really."

"She has a very sick sense of humour. Motherhood has not taken that away."

On claims that the pair are set to marry this month, he added: "Absolutely not. We haven't even started planning."
