Pictured helping to load baby gifts in a car after the event at Mayfair's Arts Club – including a Tiny Tropics Activity Gym & Playmat – the pair were all smiles.
Baby fever has certainly hit the royal family this week, with mounting excitement over the imminent arrival of Prince Harry and Meghan’s first child, and Prince William and Kate Middleton releasing pictures from Prince Louis’ first birthday.
The two princess’ appearance follows reports that Beatrice is ‘desperate’ to get married, and mounting speculation about when recently wed Eugenie will be welcoming her first child.
A source told The Express on Tuesday, 'Beatrice is desperate to get married as soon as possible and is already trying to fall pregnant. She wants a family and doesn’t care if she’s pregnant when they walk down the aisle.

'However the truth is, we could have a royal shotgun wedding on our hands.'
