And on Friday, former Atomic Kitten star Kerry went one step further when she shared a cheeky video in just her underwear.

Wearing a black bra and matching thong (and a towel on her head, obviously), the 37-year-old can be seen pointing the camera at her amazing abs as she twists from side to side.

And her 186k followers were quick to comment on the snap, as many pointed out just how great she is looking.

‘AMAZING KERRY XXXX’, wrote one fan, while another agreed: ‘You look amazing!’

And a third added: ‘You’ve just made my day’.

It comes just minutes after Kerry treated her fans to another underwear snap, this time while flexing her bulging biceps.

In the selfie, the star can be seen smiling into her mirror as she gives the camera a huge grin. And just look at those muscles!

Meanwhile, Kerry – who’s currently divorcing her husband George Kay – recently opened up on Good Morning Britain about how she’s completely changed her outlook on life since her split.

‘Going through a separation and being on my own, learning to love me, exercise, healthy eating – I’m off my bipolar medication now,’ she said.

‘I hardly ever drink, if I go out I will, but it’s very rare I go out. I have five kids so it costs you an arm and a leg – and I don’t even like kids!’
