What do you get the woman who has everything? For someone like Ellen DeGeneres, who has hosted one of the most popular talk shows for years, the list of things she needs or wants is probably pretty short. Yet her wife, actress Portia de Rossi, came up with a great idea for her 60th birthday.

In January this year, de Rossi established a center in Rwanda to help with the conservation of their gorilla population and created The Ellen DeGeneres Wildlife Fund, which will be used to raise awareness for threatened species. This gift was presented to her during the show, and the host was overwhelmed with emotion, being brought to tears. In the months since, she's been working on how to get the project going, but hasn't had to search far for investors to pitch in.

During a recent episode of The Ellen Show, she was told that there was a mystery guest who wanted to pop in and say hello. This guest turned out to be actor Ashton Kutcher, who started to talk about the company he had recently invested in. The company, Ripple, has developed an app that allows people to safely transfer money to anyone around the world, using cryptocurrency and without waiting for individual banks to approve it.

Ellen was clearly intrigued as to why Kutcher would turn up just to tell him about some technology he had invested in, but eventually, he explained what the connection was. Ashton said that Ripple was looking to help out those who are doing some good in the world, and she was the perfect candidate:

"I told them that there's this amazing human being, and all they ever do is think about other people they can give to. Whether it's in New Orleans, whether it's in Montecito, whether it's the people that come here, the people out there, you're always thinking about everyone else, and we wanted to show you that people are thinking about you."

That's when he shocked us all by offering to donate $4 million to her wildlife fund, leaving us  - and Ellen herself - speechless. Kutcher even gives Ellen the opportunity to press the button herself, transferring the millions into Rwandan francs in an instant.

This isn't the first time that the actor has shown an interest in charitable causes. Back in 2009, Kutcher and his ex-wife, actress Demi Moore, established an international human rights organization. The DNA Foundation was created to help combat the exploitation of children and the spread of child pornography.

Now, he has stepped away from acting entirely after co-founding the nonprofit organization Thorn: Digital Defenders of Children.

Back in April, he spoke to ABC News about his work, where explained that he has "been on FBI raids where I've seen things that no person should ever see". Now calling it his "day job," he is dedicated to stamping out child abuse and human trafficking across the world.
