Winter is heating up in Hollywood.
Whether they’re on tropical vacations like Natalie Portman, or getting ready for a shirtless cold plunge like Mark Wahlberg, many of Hollywood’s biggest stars are baring it all this holiday season.
Here are some celebrities bringing the heat this winter.
MARK WAHLBERG GOES TO EXTREMES WITH ‘HIGH MAINTENANCE’ FITNESS REGIMEN
“Nothing like a cold plunge in the rain. @thecoldlife @municipal. 4 am club,” Mark Wahlberg captioned an Instagram video featuring himself walking out of what appeared to be a locker room.
The “Father Stu” actor showed off his six-pack abs and his muscular arms, as he appeared shirtless in the video, wearing only a pair of short navy blue workout shorts.
“4 a.m., rain or shine. It’s raining outside — we’re still going plunge,” he can be heard telling the camera in the video. He posted a similar video of him lifting weights on Christmas morning, before celebrating the holiday with his wife and four children.
Fans in the comments section could not help but marvel at the actor’s discipline, writing, “That’s the way we do it warrior status, get it mark,” and “This man has been in shape his whole life.”
Natalie Portman had no problem showing off her figure while on vacation in St. Barts.
The “Black Swan” star’s abs were on full display as she was photographed wearing a black bikini while on the beach. The actress kept it natural with a no makeup look, choosing to wear sunglasses while in the water and keeping her hair up in a ponytail.

Portman is a mother to two children, Aleph, 13, and Amalia, 7, whom she shares with her ex-husband, Benjamin Millepied.
“I can’t decide if I want to be naughty or nice this Christmas, but I am having a hell of a good time. Merry Christmas everyone!” Halle Berry captioned a mirror selfie of herself in a black one-piece swimsuit.
In addition to the mirror selfie, the carousel of photos featured pictures of her wearing an oversized Grinch sweater, as well as one of her with her boyfriend, Van Hunt, standing in front of a large wreath.
Subsequent photos show her relaxing on a lounge chair at the beach.
