The British pop star has one very important reason to “Smile” today; she just gave birth to a baby girl! Lily and her husband Sam Cooper welcomed their first child on Friday. Lily succinctly tweeted “Totes amaze”. This was the second pregnancy for Lily and Sam,  who lost their first baby, a boy, to miscarriage in November 2010.

Lily has bravely and publicly discussed her two previous miscarriages, telling BBC: “It was a really long battle, and I think that kind of thing changes a person.” Lily and Sam married in early June, at which time she announced news of her pregnancy with the little baby girl, born today. The couple has not yet announced the name of their child, and it’s not yet known if Sam was with Lily at time of birth.
