Edoardo Mapelli Mozzi, Princess Beatrice's spouse, taunted Jeremy Clarkson by responding to the TV host's girlfriend's letter while celebrating his 65th birthday.
On Friday, Lisa Hogan, 51, shared a photo of herself and the former Top Gear host, along with a sweet message.
She captioned the photo with the following message: "Congratulations on finally achieving those Three Little Letters!"
The British property entrepreneur, who married Princess Beatrice in 2020, replied with many laughing emojis and liked the post to express his support for the celebrity pair.
It comes only weeks after Prince William was confirmed to feature in an episode of Jeremy Clarkson's Amazon Prime program.
In March, the Prince of Wales met with Caleb Cooper and agricultural expert Charlie Ireland, both of whom appear on the program, at a Duchy of Cornwall event for 60 young farmed tenants.
