Celebs in bikinis! Nicole Kidman, Halle Berry & more festive swimwear photos

"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!" wrote Halle Berry. She posed for a mirror selfie in a plunging black high-leg swimsuit that showed off her long toned legs. Her short curls were hidden underneath a cream hat.

Eva Longoria turned to celebrity-loved brand Melissa Odabash for her black tie bikini with gold detailing that offset her golden tan. "Out of office," wrote Eva, who finished her low-key look with long mermaid waves and sunglasses.

Instead of going for a swim, Dianne Buswell slipped into swimwear to enjoy a sauna with her father. The Strictly Come Dancing star shared a peek of her turquoise scoop-neck swimsuit, which she paired with a colourful necklace and a grey hat on her fiery red hair.

Rochelle Humes and her husband Marvin are enjoying an "unconventional Christmas" with their three kids in Dubai, where they enjoyed seaside dinners and playing on the beach. Dressing for the warmer weather, Rochelle layered a tiny black bikini underneath a cropped white shirt that showed off her abs, alongside low-rise jeans, brown flip-flops and an oversized black handbag.

Emerging from the water in a Baywatch moment, the Moulin Rouge star showed off her athletic figure in the wetsuit, which featured shorts and a long-sleeved top. Nicole kept her beauty look relaxed, with water dripping from her strawberry-blonde hair and waterproof mascara enhancing her natural beauty.
