Lily Allen married her boyfriend Sam Cooper at St. James the Great Church in Gloucestershire, England, on Saturday.
Wearing a white lace gown designed by French designer Delphine Manivet, the pop singer married Cooper in an intimate ceremony. Allen's father, actor Keith Allen gave her away to Cooper, who is a decorator and business owner.
During the reception, Cooper told guests that Allen is at least 12 weeks pregnant and they are expecting their first child. Friends of the couple told the Daily Mail that the singer is "ecstatic" to be expecting again, following two devastating miscarriages.
"Lily is pregnant and she is marrying the man of her dreams. She is truly over the moon and so ecstatically happy she has shed tears of joy," a source told the Daily Mail. "We have all been hoping and praying for good news and this is the best news ever."
The 26-year-old singer wrote on Twitter on Wednesday, "I'm GREAT, I'm getting MARRIED EEEEEK!!!!!"
The newlyweds did not have a pre-nuptial agreement, Allen reportedly told friends that she had no desire to have the "unromantic agreement" with her husband.
Allen and Cooper celebrated their nuptials with a "cricket tea" wedding reception and plan to honeymoon in Glastonbury, where they met in 2009. Cooper proposed to Allen during a romantic getaway last winter.
The singer was upset in February after a wedding guest leaked her invitation and wedding date to the press.
Allen is known for pop songs such as "Smile" and "LDN" but says she has "retired from singing." She is currently concentrating on her fashion career and co-founded the Lucy in Disguise label with her sister Sarah Owen. Their store is featured in the documentary "Lily Allen: From Riches to Rags," which airs on Channel 4 in the United Kingdom.
