Sharing a video to her Instagram account, the Austin Powers star is seen climbing onto a boat before dancing on the shore in the halter bikini top and bottoms with a chain detail on the hip.
Fans were wowed by the 57-year-old's physique, with one simply saying she looked "so hot".
"Wow," one commented.
"So gorgeous," another said.
"Goddess in blue," somebody else added.
"So fabulous and stunningly beautiful," a fourth claimed.
Her latest post comes after she stunned with a similar bikini, which is part of her swimwear line Elizabeth Hurley Beach, in November last year.
Many commented on the actress's natural beauty.
"Too beautiful for words," one said.
"Do you ever age?" another questioned.
In October the actress told The Sunday Times she feels younger than ever.
"I am more immature by the moment – my son is more mature than me," she said.
"I used to be grown up but I've lost it."
Elizabeth added she had not eaten processed foods for "100 years" and she doesn't eat sweets, drink a lot of alcohol or smoke.
"I have learnt to eat lighter and not so late. I think one of the most transformative things that I've done is making 50 per cent of what I eat vegetable matter," she said.
"If you have a slice of toast for breakfast, have an apple too. Counteract everything with vegetables."
