And it seems that it's such a good investment that she also has it in red. Taking to her Instagram Stories later in the day, the mother-of-three showed fans just how brave she was by sharing several clips which saw her going in to swim in a lake where the water was four degrees.
"We're going into the lake, I'm just going to check the temperature... which is four degrees," she can be seen telling the camera.
"Right, getting in," she adds as she puts on her wetsuit gloves. "I mean, it's so cold... do you see my breath? I don't know if I am going to be able to do this today. Ok, four degrees, no more than four minutes," she says before bravely jumping in.
