Stars pay tribute to Captain Tom Moore on his 100th birthday
The war veteran has raised more than GBP 30 million for the NHS by walking 100 laps of his garden.
He originally set a fundraising target of GBP 1,000 but his determination captured the public imagination and donations poured in.
He crossed the GBP 30 million mark at about 9.20am on Thursday, an hour after the RAF staged a flypast in his honour.
He was also appointed as an honorary colonel of the Army Foundation College on his special day.
McGuinness wrote on Twitter: "Happy 100th Birthday Captain Tom. 30 million raised for the NHS. Not only have you helped the NHS you also helped a Nation to smile again. Thank you and enjoy your cake!"
David Beckham wrote: "Happy 100th Birthday to COLONEL Tom, a true inspiration at a difficult time and Congratulations on being honoured."
His wife Victoria wrote: "He's just amazing. Happy 100th birthday Colonel Tom Moore."
Cowell sent Captain Tom a video message on Good Morning Britain, saying: "I hear it's your 100th birthday and I want to say that in itself is remarkable, so happy birthday, But I also want to congratulate you on everything else you are doing for the country at the moment.
"You are a total inspiration. I was going to say you're a national hero, I think you're a world hero.
"Keep doing this, please, for the next 100 years. Sending you all my love. Have the most amazing day and once again, thank you for everything you are doing for so many people. I salute you sir."
Amanda Holden serenaded Capt Tom live on her radio show Heart Breakfast, singing Happy Birthday "in the style of Marilyn Monroe to JFK".
Afterwards, he said: "You made me feel like John F Kennedy."
She replied: "We should have planned this better, I would have jumped out of a cake in a swimming costume for you."
