Shay Mitchell talks 'Mother's Day' co-stars and her top beauty tips

Shay Mitchell has long lived in the limelight, having starred in the hit TV show Pretty Little Liars since 2010. Now, she's taking her talents to the big screen, where she joins an impressive cast of female heavyweights for Mother's Day – a role which marked a huge moment in Shay's career. "I just couldn’t believe it," the face of Bioré skincare tells Hello! "I think the entire time I was like, pinch me!"

We're not surprised that Shay was so delighted – the ensemble movie also stars Jennifer Aniston, Kate Hudson, Julia Roberts. But is she nervous about joining such a star cast?

"Oh my gosh, absolutely," says the Friends fan. "I was playing opposite Jen which was quite surreal. Obviously getting to work with Garry Marshall and getting to play the new wife to Timothy Olyphant is not really a bad set up."

Since stepping on to set in Atlanta, the 29-year-old, who just celebrated her birthday on April 10 with a spin class benefiting Together One Heart, was quickly welcomed with open arms by Jennifer and the rest of the cast.

"It was them just making me feel comfortable and being a really positive energy on set," she shares. "They showed me that even with all that success and everything, you can still be excited to be where you are and very grateful."

It is clear that good genes runs in the family. For the Canadian beauty, who is back on the Pretty Little Liars' set filming season seven, it’s important though to stick with a regimen...

SHAY’S TIPS FOR LOOKING YOUR BEST:

Be disciplined: "It’s about having a regular routine," she explains. Shay makes sure to take off her makeup every night and swears by weekly exfoliation.

Indulge yourself: She likes to have mini-spa days at home – or even at work! "Bioré has these one-minute self-heating masks that I’m obsessed with," she says. "I’ll bring them to set."

Stay active: "I love boxing," she says. "I like taking advantage of being outside in L.A. because the weather is so nice here."

Find what works for you: "I really do believe in using products you trust."
