The 52-year-old actress squeezed her age-defying curves into a red hot bikini for another swimsuit shot.
Parading her slender thighs in tiny red bikini bottoms, The Royals star ensured all eyes were firmly on her.
Despite going topless for the sizzling snap, Elizabeth managed to hide her bare breast under a long cotton towel.
Stretched out on a hammock, the mother-of-one looked to be enjoying the sunny weather as she topped up her tan.
However, she protected her eyes from the blazing sunlight with a pair of stylish tinted sunglasses.
When Elizabeth shared the picture on Instagram she wished her 833,000 followers a happy Valentine’s Day and in return was inundated with hundreds of compliments.
One wrote: “Happy Valentine’s Day to the most beautiful woman in the world.”
Another commented: “Oh my! My heart just skipped several beats. Thank you! I wish you much love.”
A third gushed: “You are so gorgeous. I am a major fan,” while a fourth penned: “You’re so incredibly beautiful.”
Elizabeth recently revealed that her teenage son, Damian Hurley, takes many of her sexy bikini shots.
The 15-year-old boy is responsible for capturing some of the TV star’s most raunchy holiday moments.
“He definitely takes some, but I do have other friends that I can torture for some too,” Elizabeth said.
Speaking at the Dinosaurs In The Wild theme park preview, she added: “I’ve been in the business for a really long time so my body is something I have to take care of and think about all the time. I use as much cream as possible on it.”
Earlier this week Elizabeth wowed fans when she went braless for an eye-popping bathroom selfie.
The brunette stunner’s ample bust was impossible to miss as she wore nothing but a crochet robe.
She displayed her also toned midriff for the cheeky photography and smiled widely as she stood in front of a huge mirror.
