Nicole Richie is three months pregnant and, according to a report set for publication, now faces the stunning question: Who’s the Daddy?

The National Enquirer will report that there were FOUR men in Nicole’s life before she found out she was pregnant and sources reveal exclusively to mag which ones may take a paternity test and how this situation is about to explode.

The 25-year-old first sparked pregnancy rumours when she was photographed outside a reproductive clinic in April.

A source said: “Nicole recently underwent a series of tests, including blood and urine screenings, which confirmed she is pregnant.” The super-slim star is said to be going on a special diet for the sake of her unborn child.

Richie has been out shopping for baby products. ‘The Simple Life’ star has been on two massive sprees at hip Hollywood baby boutique Petit Tresor in the last two weeks.

On her most recent trip to the store, Nicole bought two Born Out of Necessity diaper bags and a collection of toys, including a stuffed bear, a mobile and a play mat.

Personally I don’t believe a word of this!
