Richie 'wants to keep things sexy'

Nicole Richie has reportedly bought lots of new lingerie to keep her sex life with Joel Madden exciting.

She is worried that having a baby has made their relationship less romantic, according to the National Enquirer.

The 26-year-old allegedly splashed out on a selection of "very feminine" pieces of underwear in an attempt to help revive their love life.

A source said: "They are thrilled to be parents but things have turned less romantic between them.

"Before Joel went on tour with his band Good Charlotte they were exhausted from sleep deprivation, which killed any sexual desire.

"Nicole has picked up a lot of very feminine, soft-pink items. She has stocked her lingerie drawer with hot little lacy things."

They added: "Keeping things sexy is one of her biggest goals. She wants to get him alone and lock the door for a few days!"
