Watch: Ewan McGregor welcomes baby with girlfriend
Ewan McGregor has become a father for the fifth time – and it was his daughters who revealed the secret news.
Star Wars actor McGregor, 50, and his girlfriend Mary Elizabeth Winstead, 36, had kept the pregnancy private, and fans first learned of the happy news when the newborn boy's proud big sisters posted pictures of him.
Birds Of Prey co-stars McGregor and Winstead have been dating since 2017, but had not announced that they were expecting a baby together.
His eldest daughter Clara, 25, posted photos of herself cradling her newborn brother on Sunday with the caption: "Welcome to the world little brother. Congratulations to my Dad & Mary - this is the greatest gift."
Clara's sister Esther, 19, also shared her special moment meeting her new sibling and holding him, and revealed his name is Laurie.
Sharing photos of herself dressed in a head scarf and stripy top, she wrote: "Met my little brother looking like a pirate. I recommend! Welcome to the family little Laurie."
People commenting on the photos were amazed by the shock news and some Star Wars fans made jokes about the new arrival for Obi-Wan Kenobi actor McGregor.
One person commented: "Obiwan with a new youngling added to the Jedi Academy."
Someone else wrote: "General Kenobi Jr!"
McGregor already has four daughters – Clara, Esther, Jamyan and Anouk – from his 22-year marriage to Eve Mavrakis.
He and Eve met on the set of Kavanagh QC and married in 1995, but were divorced in 2018 after citing irreconcilable differences.
Winstead was previously married to filmmaker Riley Stearns between 2010 and 2017, and this is her first child.
McGregor and Winstead met while working together on TV show Fargo, and when he won a Golden Globe for his performance, McGregor thanked both then-wife Mavrakis and new girlfriend Winstead in his acceptance speech.
Production designer Mavrakis said at the time: "I did not like his speech. I’m trying to make the best of it."
Daughter Esther, who was 15 at the time that pictures emerged of her dad and Winstead kissing, posted a song online shortly afterwards that was thought to be about her hurt at McGregor's new relationship.
