Michelle, who is still dating her The Biggest Loser co-star Steve 'Commando' Willis, was inundated with positive feedback after posting the racy photograph.
'How good does Michelle look though!!', wrote one follower, while another said, 'Yes you are missing something... Your socks!!!!'
The post comes days after Michelle revealed on Facebook that she has not 'slept a full night in seven months' after admitting Axel is 'not sleeping that well'.
