Myleene Klass marked her birthday this week with a post that showcased a white bikini that resembled the iconic one she wore on I'm A Celebrity almost two decades ago.
The former campmate, 45, took to Instagram on Thursday afternoon (April 6) to celebrate the special occasion by sharing a photo of herself enjoying some time outdoors.
She posted a photo of herself modelling a white bikini whilst stood over a bicycle in the countryside, accompanying the swimwear with a pair of sunglasses and trainers.
Myleene wrote: "45 be like... Thank you for all your lovely HBD messages, for your support and love. Here's to the next 45 years my friends. I'm off for a bike ride, a swim and some cake."
The radio host revealed that the two-piece set is part of her latest collection with fashion retailer Next, with Myleene teasing that it will be released next Sunday (April 16).

The outfit resembled the iconic bikini that she had sported during her time in the jungle on I'm A Celebrity in 2006. She donned a white bikini in a shower scene on the ITV show.
Myleene - who placed as runner-up - previously revealed that she hadn't planned to wear a white bikini and instead bought the swimwear set at the last minute.
The bikini - which attracted much attention at the time - was later auctioned off to charity by Myleene for £7,500.
Myleene's post comes ahead of I'm A Celebrity...South Africa airing later this month, which will see a host of former campmates return to compete against one another.
The starting line-up includes presenter Carol Vorderman, dancer Jordan Banjo, actor Helen Flanagan, former athlete Fatima Whitbread and singer Shaun Ryder.
And they will be joined by former boxer Amir Khan, former cricketer Phil Tufnell, former model Janice Dickinson and the Royal Family 's former servant Paul Burrell.
There had been speculation about the line-up for almost a year, with it having previously been rumoured that the likes of Myleene and presenter Gillian McKeith would return.
Although the pair - along with others like actor Dean Gaffney - don't feature in the initial line-up, a teaser hinted recently that at least three more celebrities will take part.
ITV has confirmed : "There will be many more celebrities taking part in the series but viewers will have to watch to find out who they are and when they will enter camp."
Myleene Klass looks incredible in mismatched bikini on holiday in the MaldivesMyleene was asked about potentially returning for a second stint on the reality show whilst on ITV's Lorraine last year, with her not ruling out the possibility at the time.
Asked if she will recreate her iconic shower scene, Myleene responded: "I don't know. I think I might have to tuck them in my socks. I've breastfed three babies since then."
Further discussing her stint on the show, she told Lorraine Kelly, 63: "It feels like a lifetime ago and only yesterday. It's that weird dichotomy. It was a really good time in my life."
