Wednesday star Catherine Zeta-Jones enjoyed a little rest and relaxation at the beach, but her fans are clearly never far from her mind. Zeta-Jones, who plays Morticia Addams on the hit Netflix show, shared selfies where she's posing by the ocean, assuring fans she was "warming up" to take bikini shots. The actress didn't disappoint, sharing some very classy swimsuit selfies. Zeta-Jones is 54 and looks stunning—here are the beauty tips she lives by.

Zeta-Jones loves sharing the odd beach selfie, but you won't be seeing any TMI couple pictures of her and husband Michael Douglas any time soon. "I'm not always Catherine Zeta-Jones. Most of the time, I'm just Cath," she says. "Cath is the woman who is curled up on the couch with her family. Not everyone knows her, and that's OK. I'm a very private person. I want to be a private person and I like to have a private life. I'm just not that person you're going to see posting my bathroom breaks and photos with my husband in the hot tub on social media… There's still a little bit of that boarding-school girl in me—the girl who got called down to the office for wearing too much makeup. It's kind of funny I'm launching a business based off of the very thing that used to get me in trouble."df44d9eab23ea271ddde7545ae2c09ec

Zeta-Jones relies on fruit to keep her teeth white and shiny. "I love to eat an apple after a meal, just to cleanse my teeth – they always look polished afterwards," she says. "The juice or pulp of strawberries contains malic acid which serves as an astringent and can lighten surface stains. Pineapples work the same way."

Zeta-Jones has a few products she has been using for years. "I've always, always sworn by Elizabeth Arden's 8-Hour Cream," she says. "My grandmother used to use it as the answer to literally everything. When I gashed my shins as a child, it was time for some 8-Hour Cream. Another thing I've used since I was a child is a Mason Pearson hairbrush. When I was a kid, there were some rules to having long hair, and the main one was that I had to brush it 100 times each day. My mother gave me my very first Mason Pearson hairbrush as a Christmas present, and to this day, I still use it. I've tried everything out there—I have a graveyard of brushes downstairs in my basement— but I always go back to my Mason Pearson brush."

Zeta-Jones is passionate about a good spa sessions. "I'm a big massage person, and I'm a big, big, big reflexology person," she says. "Reflexology is more beneficial than a full-body massage for me. I also like to peel my face. I try not to do any at-home extractions, but I love to get facials. I'm such a girl! I could spend all vacation in a spa, going from a body treatment to a face treatment to whatever else they have on the menu. I really could. I just love it. It makes me feel good."

Zeta-Jones uses argan oil to keep her skin supple and hydrated. "I'm finding, just from travelling from New York and being in heated hotel rooms, my skin feels like a Walker's crisp at the moment," she previously said. "But I've been using some argan oil just to saturate my skin at night, so it has some nourishment as I sleep, to start the day a little bit more hydrated. The real hydration comes from within. You can never drink too much water. No diet sodas! I think happiness is the best tonic for keeping us youthful. Being happy with who you are inside radiates on the outside."
