“17 years ago I first went into the jungle.
“On my way into camp, a show runner told me the bikini I had would strobe on camera and could I find a plain one.
“I ran into a beachside shop, asked for the plainest bikini they had and the rest is history. When I came out of the jungle, my bikini was auctioned for charity for £7500.”
Of her business success, she added: “I now have the longest running celebrity brand in the UK!!
“‘Myleene Klass’ is sold in 33 countries globally and I sell one MK item every 45 seconds at @nextofficial!”
