No, it's not a surprise new presenting duo for The One Show - the Duke and Duchess of Cambridge simply took a seat on the famous green sofa during a visit to the BBC to discuss cyber-bullying.
Prince William and Catherine tried out the sofa, off-air, while at New Broadcasting House, in central London.
The smiling royal couple met children and their parents who had helped the BBC design a new internet safety app.
The duke said tech firms had a "great deal to learn" on responsibility.
The BBC is a member of an industry-wide taskforce, set up by the prince, to tackle cyber-bullying.
After being greeted by excited crowds outside the BBC HQ, the royal couple were pictured laughing as they tried out the BBC's new app with director general Tony Hall and the director of BBC Children's, Alice Webb.
Speaking during his visit, Prince William said social media had "done more to connect the world than has ever been achieved in human history".
But he accused social media firms of being "on the back foot" when dealing with fake news, privacy and cyber-bullying.
During Thursday's brief visit, the couple also met young people who wrote and performed a new video for a campaign run by the duke's cyberbullying taskforce.
The campaign, called "Stop, Speak, Support", involves a national code of conduct for children on what to do if they come across bullying online.
It is not the first time the royal couple have visited the BBC - in 2017 they dropped in on Radio 1 and helped read the UK's Official Chart with Greg James.
And the Queen visited the BBC in 2013, when she was shown around the main newsroom.
The BBC's new wellbeing app, called Own It, aims to provide a "helping hand" to youngsters taking their first steps online and on social media. It will be available from early next year.
