The trio have helped launched a range of limited-edition charity t-shirts with fashion retailer Jacamo .
The shirts – available from small to 5XL in blue, black and grey – are on sale now and cost £15 with 100% of all proceeds going directly to the charity.
“Being able to lend our support to such a worthwhile cause is great,” said England Ashes hero Flintoff.
“I can’t stop wearing my top and hope that others will go online or in-store to get their own and show their support.
“We want to raise money, and also get more men talking about prostate cancer and if they become better aware of the risks and symptoms, then all the better”.
It coincides with the Mirror’s partnership with Prostate Cancer UK in which we have tasked the nation to get involved in our #KeepieUppieChallenge.
The Mirror’s editor Lloyd Embley set the public a simple challenge – to do more keepie uppies than him .
He managed an impressive 33, but people are jumping at the chance to beat him and make him dig into his pockets.
For every person who gets more than 33, we’ll donate £3.50 to Prostate Cancer UK – up to a total of £9,000.
Of course, that was no problem for our man Robbie as the former Wales international managed the feat with ease.
And fellow Mirror Football columnist Stan Collymore managed to smash the target in the illustrious surroundings of Wembley Stadium, where the FA Cup Final between Chelsea and Arsenal will be contested on Saturday.
Reckon you could do better? It’s not too late…
All you have to do is film yourself doing as many keepie uppies as you can.
Then share the video on Facebook or Twitter with the hashtag #keepieuppiechallenge. Tag friends you want to challenge to beat your total and make a donation to Prostate Cancer UK by texting ‘save’ to 70004 to donate £5.
Prostate Cancer UK is leading the fight against the disease, which is the most common male cancer in the UK killing one man every hour.
