After she celebrated her marriage to Sam Cooper today, the proud groom announced their happy news to friends and family at the wedding breakfast.
The couple married at St James' church in their home town of Cranham, Gloucestershire. Lily, 26, walked down the aisle with a noticeable bump in her full-length, fishtailed lace wedding dress by French designer Delphine Manivet.
Whilst her spokesman declined to comment on the news, a friend of the couple said the singer was just over three months pregnant and 'scared': 'Lily's scared, there's a long way to go - but the happiness outweighs the fear.'
Lily and Sam have been together since July 2009 but they've been friends for years.
In the past Lily has described builder Sam as the love of her life, saying: 'Sam treats me differently. He's told me he'll look after me forever. That's what I've always wanted - someone to look after me. We've never had one argument and there's nothing about him that annoys me.'
Congratulations from all at Parentdish!
