Roberts in hospital after early contractions

Julia Roberts is in hospital in Los Angeles after experiencing early contractions.

The 36-year-old was escorted by husband Danny Moder to the hospital after she began the contractions - about two months ahead of schedule.

The actress is expecting a set of twins, one boy, one girl in early January.

She and her unborn children are said to be fine but she will likely be confined to bed rest until she delivers.

The Oscar-winner had been planning on making the rounds in the coming weeks to promote her two new movies, 'Closer' and 'Ocean's Twelve'.
