Wearing a short black dress that showed off the royals toned legs, Beatrice turned the casual look sophisticated by wearing a long red satin coat, suede black pumps and a preppy headband.
Bea, 30, is believed to have met her boyfriend, Edoardo, at her sister Eugenie's wedding in October last year, and they've been on the fast-track to forever ever since!
Edoardo, a father-of-one, is already making himself at home amongst the Royal Family, a source recently revealed to The Sun.
“Edo has moved in with Beatrice at her apartment in St James’s Palace and spends most of his time there,’ a source told the newspaper.
“I don’t know if he has actually got down on one knee with a ring yet but they are openly talking about marriage and it will either be later this year or possibly early in 2020.”
