It’s a girl!

Ali Larter and Hayes MacArthur are parents for the second time after welcoming a daughter on Thursday, Jan. 15, the actress announced on her website Monday.

“We couldn’t be more excited to share news of the arrival of Vivienne Margaret MacArthur,” the Legends star wrote alongside a photo of the newborn snapped by Dad.

“She came bearing gifts for her brother: Batman sheets and lots of gummy bears!!! 7.5 lbs. of love.”

Vivienne joins the couple’s 4-year-old sonTheodore Hayes, at home.

Larter, 38, held off on announcing her pregnancy until she could get a little help from friend Jimmy Fallon.

“[Three years ago] I came on and I was pregnant and it went so well, and I said to my husband, ‘I’m going on Fallon, you know what that means — gotta get pregnant!'” she joked during her August appearance.

And although the sibling bond seemed to be off to a good start — Larter shared that her son was looking forward to watching Batman with the new baby — the mom-to-be later joked she had resorted to winning over the soon-to-be big brother with a few treats.

“I’ve started giving him presents from his little baby brother or sister,” the actress told PEOPLE. “We’re definitely working him, bribing him, whatever we have to do to make sure he doesn’t sneak into that crib and dangle that baby by its feet.”

It’s set to be a busy year for the couple — Larter’s show was recently renewed for a second season, while MacArthur will be a regular on the upcoming TBS comedy Angie Tribeca.
