James has since deleted the post from his Instagram page, while Ola has edited her caption to remove the remark about her “shrinking” waistline.
Express.co.uk has contacted representatives for James and Ola for comment.
Ola previously said of the pair’s fitness plan: “There is no gym, no equipment and no stress. We put the plan together in our kitchen, which is only two metres square.
“It was so lovely to dance again, so this plan is devised using our favourite dance moves made simple and combined with functional exercises, all to music, so you are shredding pounds while having a blast.
“The exercise takes only 15 minutes a day. This was so important to me as a mum, that it was quick — and Ella can do it too.”
James added to The Sun: “We spent our whole lives looking our best when we were dancing so we were like, ‘Let’s start dancing again’.”
