Nicole Richie won't let fiance help plan their wedding

Nicole Richie has joked fiance Joel Madden has no say in their forthcoming nuptials.

The reality TV star and the Good Charlotte rocker - who have two children, Harlow, two, and five-month-old Sparrow - announced their engagement last month but admit Nicole is the one in charge of the plans.

Talking about the wedding, Joel said: "It's the same thing as our engagement, we're kind of doing it at our own pace. We have no idea right now."

Nicole then quipped: "Like he has any say."

The couple are also disagreeing what kind of wedding they want.

Joel added: "According to her we'll have a really big wedding. According to me, it will be really small."

Nicole and Joel attended last night's Oscars (07.03.10) together and joked they were set to tie the knot imminently.

When asked about the date of their big day, Nicole deadpanned: "It's tomorrow."

Joel - who performed a DJ set at the ceremony - quipped: "I thought it would be cool to do it here."

Although their engagement was announced last month, the couple had secretly been engaged for some time.

Joel tweeted recently: "Yep. I'm engaged. Very happy.

"Yeah we've been engaged for a while so your all kind of late on that. But Thanks for the hooplah all the same (sic)."

The couple denied that they had plans to marry as late as last year, and were in no plans to rush into tying the knot.

Nicole said: "One day I would love to get married. It's not something we're talking about right now. If my kids ask me to get married, I'd get married."
