Tamera Mowry-Housley Feels 'Weird' Watching Her Own Holiday Films but Her Family Views While She Cooks for Christmas (Exclusive)

Tamera Mowry-Housley has a lot to look forward to this Christmas!

As she teams up with VistaPrint to make her holiday prep easier (and launch an all-new collection), the Sister, Sister actress, 46, exclusively tells PEOPLE about how she plans to celebrate the winter holiday next month.

"My husband [Adam Housley] and I have been doing this since we've been together, so it's about 20 years. We start on Christmas Eve," Mowry-Housley, 46, says. "We invite everyone to our house that maybe doesn't have a place, their family is not around. We bake cookies and we have a little, it's not like a big party, but a get-together."

"Every Christmas, we invite our entire family. This year my sister's invited, my brothers, my mom, my dad, pretty much everybody in the family," she continues. "And we make Christmas beef. It usually ends up being a roast beef with mashed potatoes, green beans. Those are some of the staples, with a Christmas drink that I look for. We just get together and enjoy each other."

Mowry-Housley notes that some of the traditions, beyond indulging in delicious foods and "decorating the Christmas tree," include having "our television, 24/7, for 48 hours" playing Christmas movies — even her own.

"I'm a little bit weird watching my own stuff, even though I produce them. So what I do though is I put it on for everyone else to watch it while cook or bake," she admits. "But we do watch them. My mom watches them literally every single one, every single year, and tells me which ones are her favorite. And my husband even sits down and watches."

"My daughter's favorite so far has been Scouting for Christmas, the most recent one. She loves it. She loves it. Loves it," she adds, also sharing that starring in holiday films annually has "become a Christmas tradition" for her as well.

This year's gathering is extra special for Mowry-Housley, who shares that her parents will be at the celebration. It's a big deal as it marks the first time the former couple will be together for the holiday since their divorce in 2015 after 40 years of marriage.

"I'm really, really excited about this Christmas because our entire family is invited. My parents are divorced, and it'll be the first time we spend Christmas under my house with my mom and my dad together in my house," she says. "I'm really excited about that. I'm freaking out."

Ahead of the Christmas season, Mowry-Housley is getting her ducks in a row with the help of VistaPrint, whom she's partnering with for an exclusive collection she curated, featuring her favorite budget-friendly, customizable holiday cards. The Real alum even benefitted from using the E-commerce printing company to develop her annual holiday card.

"Every year, my family, we really look forward to just diving into holiday traditions. We've been doing holiday cards for, I want to say this year, it'll be 12 years. It's pretty cool. It's something that I get so excited about because it's our way as a family to spread the joy, the cheer, and the love to our family and friends that maybe we haven't seen throughout the year," she says.

"We really take it seriously in the sense that we want it to feel warm, loving, and personal. We have friends and family that reach out to us when they move and they say, 'We don't want to miss the card this year.' So it makes us feel really, really good that not only have we created a family tradition amongst the Housleys, but we've created this tradition amongst our family and friends that they can't wait to be a part of," she continues. "This year, it was very, very busy in the month of October. Having VistaPrint really, really helped me as a busy mom because it just makes it that much easier to design your ideas. I've used VistaPrint in the past 12 years doing a holiday card, but also we use it for our business."

Mowry-Housley adds, "We have a coffee shop and yes, a winery and a tasting room in Napa. So I've already known how wonderful the VistaPrint experience is. So this was a natural collaboration, which I tend to like to do. I just loved how VistaPrint just makes everything so easy to personalize and design because in gifting, for me, I want people to feel that. I want it to feel genuine."

The Tamera Mowry-Housley Holiday Collection is now available to shop via VistaPrint's website.
