The Scottish presenter was hit by a "hideous" illness and forced to leave the ITV set of her daytime talk show as Ranvir Singh readily stepped in.
On Wednesday morning, ITV tweeted: "Very sorry to say @reallorraine has reluctantly had to go home poorly, get well soon Lorraine! @ranvir01's saving the day and on her way, and @GMB's Kate and Ed have what's coming up (And don't worry, Ed decided against doing his Lorraine impression)".
Lorraine added her own explanation as she also posted on Twitter. She said: "When you have to be sent home from work early in the morning because you are suddenly attacked by a hideous bug and were looking forward to interviewing @adamlambert.
THAT! Beyond disappointed but imagine if I had infected him !!!!!!"READ MORE: Lorraine Kelly sent home from ITV show as replacement announcedThe presenter, 63, was also absent from Thursday and Friday's episodes of Lorraine and remained silent on social media.
