The Littlewoods model, designer and singer, 35, couldn't hide her excitement just before jumping into the water with the highly dangerous creatures. Rather you than us, Myleene!
Sharing pictures of herself in a gorgeous cut-out black bikini - available soon from Myleene's Littlewoods range - Myleene was all smiles as she basked in the sun onboard a boat and prepared to meet some wild sharks in South Africa. Eek!
Alongside the series of sun-bleached selfies, mum-of-two Myleene wrote: "Off to see something with a bigger mouth than me#jaws #shark #southafrica.
"Going in #fishfood #shark #southafrica."
She also posted a "shark selfie", with the hashtag "jamesbond".
We definitely think Myleene - and her smokin' hot body! - would make an amazing Bond girl!
