"Do you know how I found the two of you?" DeGeneres teased during the interview. "Meghan Markle sent me this video. She texted me and said, 'What do you think of this, how great is this girl?'"
The pair looked visibly shocked with Anaé hiding her face in disbelief, as the television audience cheered the performers.
DeGeneres continued, adding: "I know, I said 'I can't wait for everybody to see how amazing this is'."
DeGeneres has long been friends with the Duke and Duchess of Sussex and recently met their newborn son, Archie, during a trip across the pond.
"I just want to say: It was an honour for them to meet me," the 61-year-old joked, going on to describe the royal couple as "so down to earth".
When Prince Harry recently came under fire for using private jets amid the climate change crisis, the talk show host famously defended them via social media.
"Portia and I met Prince Harry and Meghan in England to talk about their work on wildlife conservation," she wrote on Twitter. "They were the most down-to-earth, compassionate people. Imagine being attacked for everything you do, when all you’re trying to do is make the world better."
