Jeremy, Addison, and… Ezer makes three! On Oct. 20, Shameless star Jeremy Allen White and his longtime girlfriend, Addison Timlin, welcomed their beautiful baby girl, Ezer Billie White, to the world!

“Welcome to the world baby girl, it just got so much brighter,” Addison wrote on an Instagram, along with two precious snapshots of herself and Jeremy each holding their newborn daughter — who, by the way, has a impressively full head of hair!

Naturally, fans of the pair flocked to the post to share their love, support, and congratulations. “OMG! What a great name! Congratulations to you both,” one user commented. “This is the cutest thing I’ve ever seen. I’m gonna cry! So much love and blessings to you both. Congrats,” added another.

Of course, someone made sure to include a Shameless reference and wrote: “Ezer Billie White Gallagher, right? Gotta represent your fam on the South Side, Lip!”

Jeremy and Addison announced their baby news back in June and even then, it was clear that they were both so excited to become parents. “We made a baby and my heart is bursting at the seams. Today is my birthday but my wish already came true. This is 27 and the best is yet to come,” Addison wrote at the time.

ICYMI: Before they became #RelationshipGoals, Jeremy and Addison were first co-stars and then friends. In fact, the newly minted mama has shared several #tbt photos of the couple from their younger days, including a snapshot of the pair on the set of Afterschool in 2008. They were both 17 years old at the time.
