London, June 12 (IANS) Singer Lilly Allen married her fiance Sam Cooper in a traditional ceremony in the English countryside where the builder announced they are expecting their first child.

Allen, 26, is reportedly 16 weeks pregnant. Cooper decided to include the announcement in his wedding day speech Saturday after they went for the 12-week scan and were told the baby was developing healthily.

"This is the happiest day of Lily and Sam's lives, and they are so in love. This is the icing on the wedding cake!" femalefirst.co.uk quoted a source as saying.

Allen and Cooper tied the knot at the St James the Great church in Gloucestershire, with the singer wearing a lace wedding dress designed by designer Delphine Manivet.

Allen has had two miscarriages. The first time was in January 2008 when she was dating "Chemical Brothers" star Ed Simons. She lost her second baby in November 2010 when she was six months pregnant with Cooper's child.
