As March fast approaches it can only mean one thing - Red Nose Day is nearly here! This year's event takes place on Friday 15th March and Robbie's been doing his bit for Comic Relief by donning one of this year's official t-shirts.
Designed by Stella McCartney, the t-shirts feature icons including The Beatles, Tommy Cooper and Marilyn Monroe and are available exclusively from TK Maxx stores across the UK and online now.
In sporting the nifty number, Robbie's supporting the annual Red Nose Day campaign to 'Do Something Funny For Money', with all profits from the sale of each t-shirt going towards helping people living incredibly tough lives across Africa and in the UK.
Robbie's already a regular contributor to Comic Relief, set up Give It Sum back in 2000.
If you're in the UK and would like to join Robbie by buying your own t-shirt, you can pop into your nearest TK Maxx or check out the selection online here.
Wherever you are in the world, you can donate to this truly worthy cause at any time. Click here if you'd like to make a donation to Red Nose Day online.
