Jimmy Fallon is set to join the list of celebrities donating money to those affected by Hurricane Harvey.

The tropical storm ripped through Houston, Texas, last week, and since then, a number of stars have stepped forward to send their prayers and generous donations to those left without homes or stranded by the devastating flooding.

On Tuesday (05.09.17), the 42-year-old talk show host announced during his monologue on 'The Tonight Show starring Jimmy Fallon' that the show would be joining the relief effort by donating a whopping $1 million to the fund set up by basketball star J.J. Watt, which aims to provide ''food, water, and supplies to the victims.''

Jimmy said: ''Last week we saw the devastating effects of Hurricane Harvey on the state of Texas. But in the face of this tragedy, we saw good.

''We saw communities banding together. Neighbours helping neighbours. Strangers helping strangers. So many heroes - people like Mattress Mack, who opened up his stores and showrooms for those who needed shelter. The group of people who formed a human chain to save a man from a flooded SUV ... And J.J. Watt from the Houston Texans, who has raised over $18 million dollars to provide food, water, and supplies to the victims.

''I'm proud to say that our show, 'The Tonight Show', is donating one million dollars to J.J.'s fund. Thank you, J.J.''

The star joins the likes of Taylor Swift, Sandra Bullock, Beyonce, Pink, and Justin Bieber in donating large sums to various organisations aimed at helping those affected by the storm.

Celebrities aren't just helping with monetary donations either, as singer Rita Ora spent time volunteering in a centre in Dallas, Texas, last week, and Miranda Lambert's foundation MuttNation has been working to rescue lost pets who have been left stranded by the disaster.
