Ryan Reynolds has urged his fans to help those affected by Hurricane Harvey and Hurricane Irma

Taking to his social media accounts on Saturday (09.09.17), Ryan posted a picture of himself in his 'Deadpool' costume with a t-shirt over the top reading "Hope. Heal. Rebuild", and told fans how they could help the cause.

He captioned the snap: "Let's help those affected by Hurricane Harvey and Hurricane Irma. Support the incredible ground efforts of Americares emergency response teams with this snazzy t-shirt. Get one by clicking link in my bio. OR... Skip the f***ing t-shirts altogether! Donate directly at Americares.org or use CharityNavigator.org to find the charity of your choice. (sic)"

The 40-year-old actor isn't the only star to get involved with the relief effort either, as celebrities such as Leonardo Di Caprio, Taylor Swift, Jimmy Kimmel, Rita Ora, Kevin Hart, Justin Bieber, the Kardashians, and Miranda Lambert have all donated time and money to helping the victims get back on their feet.

'Formation' hitmaker Beyonce has also helped the cause, with her church pastor Rudy Rasmus praising her work as "a real blessing" to the people of Houston, Texas.

He said: "Beyoncé is extremely private and has done a lot that she has requested that we don't announce and publicise over the years. So right now I think to each his own, she has always taken a position to help this city in its time of need, and now is no different. She has really stepped up and it's been a real blessing for us."

Rudy - who is the pastor for St. John's Church in downtown Houston - has been working with BeyGOOD to gather supplies, which will be taken to those in need once the heavy rainfall clears.

He added: "We are right now mobilising to gather as many supplies as we can, knowing that in the next few days when the skies start clearing, people are going to be in intense need of items that of just right now have already lost in their homes due to the flooding."
