Fans of the ITV show took to social media to reveal they were “sobbing” and “in tears” as Rihanna asked her step-dad to adopt her.
Nick had headed to watch the show live alongside wife Katie, when was surprised with the question from their daughter.
He was brought down in front of the live studio audience – looking in shock – before Rihanna appeared from behind the scenes.
She then read an emotional message to Nick before asking the question: “Will you adopt me?”
Nick broke down in tears in the studio, leaving Ant, 47, and Dec, 46, holding back their emotions as they let the father and daughter have their big moment.
But fans at home revealed that they couldn’t control their tears, as they were left “sobbing” over the scenes.
One penned on Twitter: “Wow I’m a grown man sat here crying my eyes out,” as a second said: “Blubbering mess thanks to Ant and Dec.”
