Martine McCutcheon showcased her slim figure as she soaked up the sun in a black bikini during her family holiday on Monday.
The actress, 45, took to Instagram to share a clip of herself playing table tennis on the beach with her son Rafferty, seven, and wore a high waisted two-piece which displayed her weight loss.
Martine shared an entertaining clip filmed by her husband Jack McManus which showed Rafferty launching the ping pong ball across the table- only for it to accidentally hit her cleavage.
She wrote: "A Bird whistle, a table tennis ball between the maraca's - & a little champion! Hahaha!!"
And Martine looked ready to hit the beach again on Tuesday as she looked effortlessly chic white beach dress which was adorned with a blue pattern.
She teamed the look with sunglasses and a white hat and held a grey beach bag in her hand as she posed in front of pretty flower bed.
She captioned the shot: "One of the things I love most about holidays, is the lack of decisions to make! And the ones you DO make are so lovely… Pool or Beach?
"Bikini or one piece? Dress, shirt, or kaftan? Where shall we go for dinner? I’ve lost all sense of time and love it. I’m a typical Taurean in that I like to do things well but at my own pace - I hate being rushed and the holiday time zone definitely suits me!
"We don’t go abroad often where it doesn’t involve work of some kind and I’ve decided I want to do it more often! It’s SO good for the soul."
The Perfect Moment singer has just launched a modelling career after being signed by the prestigious Elite model agency, which represented fashion icons Cindy Crawford and Naomi Campbell.
Speaking about the secret to her stunning physique, Martine told Sunday magazine: "It’s taken me such a long time to look through all the stuff that’s out there, and just do what works for me.
"So it’s not as simple as just going on a crazy diet. I just feel like it’s really important to encourage women to just be the best version of themselves.
"The 80/20 rule is what works for me."
Martine explained: "For 80% of my week, I will have mainly just healthy proteins, vegetables and fruit, organic and veggie juices, and Flora ProActiv spread.
"And then I’ll have treats 20% of the time – I’ll have that slice of pizza, chocolate or a G&T to celebrate a friend’s birthday.
"I’ll do it because I know that for most of the week, I’ve been doing the good bits for my heart."
Martine has worked hard to lead a healthy lifestyle as she suffers from a number of invisible health conditions, including Lyme disease, chronic ME and fibromyalgia.
"When I get symptoms or when my body starts clanging, it's a sign for me to pace myself, rest," she previously told Hello!.
