Princess Beatrice's husband reacts to Kate Middleton's video

It's not often that Kate Middleton steps out to perform royal duties since her cancer diagnosis, but when she does, royal fans can't help but swoon over the wife of Prince William. 

Having completed her chemotherapy in August last year, she's been gradually returning to royal duties. 

On Tuesday, June 10, the future queen made a rare appearance in London for a special visit to the V&A East Storehouse, marking her first public outing since the Prince and Princess of Wales returned from their family break with their children. 

A video of Kate Middleton's royal engagement, shared on the official Instagram account of the royal couple, garnered over 30,000 likes. 

Among the thousands who reacted to the video was Edoardo Mapelli Mozzi, who showed his support for the senior royal by pressing the heart button. 

Mozzi is married to Princess Beatrice, the daughter of Prince Andrew and sister of Princess Eugenie.
