The author, 64, wrote on Twitter: "I'm so achy today. No Covid but whole bod in need of a recharge." Ferne's fans weren't convinced that she was Covid-free, with one saying: "Hope you are better soon. If you have done a covid test, remember it is better to do it in the throat and not nose," while another advised: "I tested negative even though I had sore throat and achey . Did another test later in the day and was positive."

Another follower messaged Fern to ask if she's still into cycling, with Fern responding: "Having a break but must get started again."
Fern has long been a keen cyclist, noting in 2011 that she was "cycling like mad" yet not losing weight, which was what led her to have a gastric band fitted in 2008, which helped her shed five stone, going from a size 22 to a size 12.
The former This Morning presenter has had a rocky ride with her health, though. In 2016 she contracted sepsis (defined as a life-threatening reaction to an infection, per the NHS) after becoming seriously ill from a routine hysterectomy.

"So I'm wishing you a very happy future. Congratulations and keep going."
