The 45-year-old musician and radio host was pictured during a shoot in South Africa for her clothing brand sold at Next.
She wrote on Instagram: “And that’s a wrap! A fleeting fun, few days in South Africa shooting more of my Swim and Beach collection.”
Myleene recently praised her collection with Next, and spoke about her highly successful clothing range.
She said: “Proud to lead the charge. In the words of Louis Armstrong; A lotta cats copy the Mona Lisa, but people still line up to see the original!
“Thank you to my customers, (my girls), old and new who’ve stuck by me, grown with me, introduced their kids to me and chosen to wear my designs.
“In a sea of choice, I’m honoured. As a working woman myself, I never take it for granted that you decide to dedicate your money to my designs.
“Know in turn, I make sure every fibre, stitch, design is created not to disguise or hide you, but to celebrate you and help you feel great. Especially on the beach. This season of bold print and vibrant colour is especially for you x.”
Klass started her collection after her white bikini stint on ITV’s I’m A Celebrity in 2006.
She later auctioned it off, raising £7,500 for charity.
