It's a girl for Lily Allen and husband of 5 months, Sam Cooper! The pop singer reportedly welcomed her first child Friday.

Allen has yet to confirm the birth -- though she did write "totes amaze" on Twitter Friday -- but that hasn't stopped her pals from chiming in with well wishes on the site.

Her friend Sam Chew wrote (via People.com): "sending out love to lily, sam and mini cooper...... YES."

Another friend, Charlie Condou, responded to a tweet asking if the news was true. He wrote: "She has indeed, a little girl"

Allen and Cooper got hitched in England in June and announced the pregnancy at the reception.
