That's Mrs. Cooper to you!
Three days after swapping vows with her business owner boyfriend Sam Cooper, singer Lily Allen is officially settling into married life. The newlywed -- an active participant on the microblogging site Twitter -- has already changed her account handle to reflect her new last name.
"I had the most amazing wedding, thank you to everyone who went to such extraordinary efforts to make it that way," Cooper (nee Allen) wrote.
Adding to the singer's special day? She and her groom, 32, announced to wedding guests that they were expecting their first child together.
"Sam announced it during his [wedding] speech," a source close to the couple confirmed to Us Weekly. "They are over the moon -- this is the best possible news on the best day."
