Olivia Wilde and her fiance Jason Sudeikis have welcomed a baby girl.
Actress Olivia announced the news online, saying that their new arrival was born on Tuesday, International Day of the Girl.
The thrilled couple have called the baby Daisy Josephine Sudeikis.
Olivia, 32, posted a photo of the bay on Instagram with the message: "There goes the neighborhood. Daisy Josephine Sudeikis. Born, like a boss, on #internationaldayofthegirl.."
Daisy joins big brother Otis, who is two.
Olivia announced she was pregnant in April by posting a touching photograph online of herself sitting in bed with Otis.
The Vinyl star was clutching her tummy, and the toddler was copying his mum. The caption said: "Matching baby bumps."
Olivia revealed last month that her new arrival would be a girl.
