The 27-year-old’s mum Kym was diagnosed with acute myeloid leukaemia last August.

At the time they were told that her only chance of survival was a stem transplant from a stranger, prompting the TOWIE star to launch a campaign to save his mum.

Thanks to the #SaveBobbysMum appeal, a donor was found and Kym has had the surgery and is now recovering at home.

Grateful Bobby took to Twitter this afternoon to thank the stranger who gave his mum a second chance.

He wrote: “Somewhere there is an amazing person that registered with @AnthonyNolan and was a match for my mum, I will never be able to thank them enough.”

His mum might have found her donor, but Bobby’s work for Anthony Nolan isn’t done.

He said: “Without the work of Anthony Nolan, and the hero who donated their stem cells, there would be little hope, it doesn’t bare thinking about. I genuinely feel like there is an angel on this earth, I hope one day I can thank them in person.”

Ann O’Leary, Head of Register Development at Anthony Nolan said: ““It’s our goal to save the life of everyone who needs a transplant so it’s wonderful that Bobby is now carrying on the fight against blood cancer and urging even more people to come forward and support the work of Anthony Nolan – in particular young men.”

If you’re 16-30 and in good health you can join the register online at www.anthonynolan.org. You can also donate £3 to Anthony Nolan by texting HOPE to 80010.
