Richie denies working with Rihanna

Nicole Richie has denied enlisting Rihanna's support in a bid to launch her solo career.

Rumours that Richie had approached the 'Disturbia' singer and Kelly Osbourne for advice were sparked by US reports last week.

However, the Simple Life star insisted that she has no plans to record an album anytime soon.

"That's not true. Although I think that Rihanna and Kelly Osbourne are very talented, that's completely false," she told People.

"I do eventually [want to record an album], but right now I have a lot on my plate. I've been working really hard - going on auditions for acting, doing design for my line, and being a mum - so that pretty much takes up my days."
