Sofia Richie is officially a mom — she and her husband Elliot Grainge say their bundle of joy arrived this week.

Lionel Richie‘s daughter gave birth to her own little girl … Sofia says she gave birth on Monday, which she calls the “best day of my life.”

And they’ve already got a name … Eloise Samantha Grainge.

Sofia announced in January she and Elliot were expecting … sharing with Vogue that she would give birth sometime in May or June, as she was set to have a Gemini baby. Well, she juuuust missed on that guess!

Monday was May 20, which makes baby Eloise a Taurus, officially. One day later and she would’ve been a Gemini.

While Sofia was excited to become a girl mom, she admitted to the publication that she and her hubby were initially convinced they were having a boy.

She shared … “So it was a true shock. My dream in life is to have a daughter [though], and Elliot is really excited for a girl too. I think it’s so typical for boys to want boys, but he has a lot of sisters. It was really sweet. He’s very sensitive.”

Sofia and Elliot tied the knot in April 2023 in a lavish ceremony in the South of France … which is around the time the pair casually started trying to get pregnant. She first wondered if she was expecting after getting sick at a fashion show in Milan … later confirming her pregnancy after grabbing a pregnancy test in L.A.

The rest, as they say, is history.

Since announcing her pregnancy, Sofia has happily shared her baby bump with the world … regularly posting updates to her social media. In fact, earlier in May, Sofia confirmed on Instagram she was 9 months along, describing her journey as “bliss.”

Congratulations to the new parents!!!
