Baby Evelyn Penn Willis weighed in at 8lbs, 10oz. Both mom and baby are said to be healthy and doing beautifully.
Us exclusively broke news back in December 2013 that the couple were expecting another bundle of joy. Heming-Willis, who tied the knot with the Die Hard actor, 59, in 2009, debuted her growing belly while shopping at a local farmer's market in L.A. that month. The pair are already parents to daughter Mabel, 24 months.
He's "very present and amazing with Mabel," an insider told Us of Willis at the time. While the second-time mom is "very devoted" and "supportive of him, so when he needs to work she steps up her mommy game."
In anticipation for their new addition, the spouses traveled to the Turks and Caicos Islands for a babymoon at Willis' place in Parrot Cay last February. "#BabyMoon2014 Photo: B. Willis," Heming-Willis captioned on her official Facebook page, along with a baby bump snapshot of herself.
The little one is the fifth child overall for the actor, who shares daughters Rumer, 25, Scout, 22, and Tallulah, 19, with ex-wife Demi Moore. As it happens, Moore's second ex-husband Ashton Kutcher is preparing for first-time fatherhood: His fiancee, Mila Kunis, is pregnant with their first child.
