Doctor Who stars David Tennant and Billie Piper have helped raise a whopping £20,000 for a kids' charity.
The actors attended a Children In Need fundraiser in Cardiff which was billed as a "Doctor Who Galactic Dinner".
The show's writer Russell T Davies was also there and took charge of an auction of Doctor Who memorabilia, which attracted bids of up to £4,000.
The cash will go towards improving the lives of young people. This year, the charity will give out £35m in aid.
More than 250 people went to the galactic dinner.
Billie, who plays the Doctor's assistant Rose, said: "Everyone had an amazing night."
