Good Morning Britain's Susanna Reid battled through a sore throat on Monday, saying she has not taken a sick day since 2005.
The ITV presenter apologised to viewers for her gravelly voice on air after revealing her co-host, Piers Morgan, was "furious" that she was ill.
Reid said although she was ill with a cold, she was "struggling on", adding: "Do you know what, I'm so stubborn. I won't take a sick day."
She told viewers she was breathing like Darth Vader and had a " very sore throat like razors".
Morgan put on a face mask to protect himself from her germs, telling her: "Professionally I 'm right behind you, personally I don't want to get it. I'm going to have to wear one of these for the show."
She told Morgan her last sick day had been back in 2005 and joked that perhaps he could wear the mask more often: "Will that actually stop you talking Piers because if it does perhaps you could wear it every morning."
Thanking viewers for their messages of support she Tweeted: "Thanks for all your lovely messages. Even @piersmorgan showed his sympathetic side! Going home to sleep. Normal service resumed tomorrow."
ITV presenter Lorraine Kelly said she thought Reid was a "real trouper".
She tweeted: " She's not well but never takes a day off. My kind of woman."
Viewers sympathised with her more than they did Morgan, with one tweeting: "If you feel the need to cough I wouldn't think any less off you if you did in the direction of @piersmorgan."
Another tweeted saying: "Poorly but looking gorgeous today Susanna."
