Naomi Watts is honeymooning in the lap of luxury after marrying husband Billy Crudup in a lavish Mexico City ceremony over the weekend.

And the Australian actress, 55, has now given fans glimpse at her very glamorous honeymoon attire. 

Posting to Instagram Stories on Thursday, the King Kong star shared a photo of herself posing in the mirror wearing a high-waist orange print bikini that showcased her svelte physique and long legs. 

The two-piece ensemble is designed by luxury brand Ulla Johnson and is worth a whopping $620. 

Naomi paired her pricey swimmers with a $663 sun hat by Gigi Burris Millinery, red-framed sunglasses and a red clutch bag by Tori Burch worth $375.

Looking effortlessly chic, Naomi added a festive flare to her look with a slick of red lipstick and an elegant gold necklace.  

Her stylist also uploaded a photo of the Mulholland Drive star posing in swimwear on her honeymoon, this time wearing white one-piece that perfectly flattered her slender physique. 

The $300 halter-neck swimsuit by Maygel Coronel featured a plunging neckline, ruching around the waist and a statement flower embellishment at the centre.
