Mila Kunis and Ashton Kutcher are officially parents.

The couple welcomed a baby girl, Wyatt Isabelle, on Tuesday evening at Cedars-Sinai Medical Center in Los Angeles, according to TMZ. Kunis and Kutcher arrived at the hospital unattended at 6 a.m. and were taken directly to the delivery room.

The baby is the first child for both parents, and Kunis couldn't wait for motherhood.

"I have never wanted to be the person who only has business on her mind. To me, this job has always been a hobby that turned into a great profession, but I don't eat and breathe acting," she told W magazine in July. "I'm sure Meryl Streep has a very different point of view. But I'm excited about being a full-time mom."

Kunis' acting job is what brought her together with fiancé Kutcher. The two met on the set of their Fox comedy "That '70s Show" in 1998. The actress shared her first real kiss both on-screen and off with Kutcher, and the two even attended the prom together (on the show, of course).

"I went through everything embarrassing that a girl can go through in front of my fiancé. There's no question that he's seen the worst. I find that comforting," Kunis said.

The couple has not announced a wedding date. A new baby should keep them busy for awhile.
