Life is imitating art for new mom and "Up All Night" star Christina Applegate.
On the NBC comedy, Christina's onscreen daughter is about to turn 1, and off screen, her daughter Sadie (with fiance Martyn LeNoble) is also about to hit the 1-year mark.
"It's so weird how the show really does parallel my own life," Christina told AccessHollywood.com's Laura Saltman during a visit to the "Up All Night" set in Los Angeles on Friday. "Sadie's going to be 1 next week, so it's all sort of culminating at the same time."
For her daughter's birthday party, Christina said she and Martyn are keeping it simple as Sadie is too young to remember the fete.
"I only invited people with babies, so we've got about 10 babies and we're gonna do some things for the babies," she told Laura. "Do you remember your first birthday party? No! It's a photo-op. There is going to be an activity that Sadie actually really enjoys, so, you know, we'll be doing that, and that's it. Two hours, feed them some yummy stuff ... and then everybody leaves."
Christina also said (similar to her character on the show) that her home life has become completely centered around her baby - so much so that she and her composer beau forewent purchasing birthday presents for each other this year.
"For my birthday I [told him], 'Please, no gifts,'" she told Laura. "We both know that the other person's working so hard -- he composes all of the music for the show and he's working his butt off, and I'm working my butt off, so we both understand. Everything's about Sadie anyway."
As for wedding plans (the couple became engaged in February 2010, but has yet to tie the knot), Christina said their hectic schedules are interfering with nuptials.
"Of course [we will get married], but the schedule, the way that it is -- it's just almost impossible. It really is. It's insane," she said. "We kind of thought about, seriously, like a city hall thing. Like just going and doing it and being done with that part of it, then having a party six months from now."
While the actress would like to be married, she's not concerned about their marital status as she says having a child together is stronger than a marriage document.
"For me [getting married] doesn't add to the fact that we love each other and that we're going to be together and that we have this incredible human that bonds us for life -- literally for life," she said. "So, I think we're good.
