Lily Allen has taken her husband's surname - on twitter.
The 26-year-singer tied the knot with building firm owner Sam Cooper on Saturday and she has now changed her username on the micro-blogging site from @lilyroseallen to @MrsLRCooper.
Although she didn't mention the name change in her tweets, she did thank everyone who was involved in making her wedding a special day.
She tweeted: "I had the most amazing wedding, thank you to everyone who went to such extraordinary efforts to make it that way."
It is not yet known if she intends to refer to himself as Lily Cooper professionally.
The couple tied the knot in front of their friends and family at the St James the Great church in Cranham, near Stroud, Gloucestershire, South West England.
Later in the day at the reception, which was held in the grounds of the newlyweds' £3 million (NZ$6 million) mansion, Sam announced that Lily is pregnant.
The loved-up pair are due to go to the Glastonbury Festival next week for their honeymoon.
Lily, 26, and Sam first met at the music event in 2009 and are set to stay in luxury teepees at the camp site.
Glastonbury organiser Michael Eavis said: "I'll set her up a special tent - she'll have the best treatment."
