Days after Ava Phillippe escorted her twin-like mother, Reese Witherspoon, to the London premiere of box office hit A Wrinkle In Time, the 18 year-old has been spotted out with similarly famous offspring.

On Monday night the daughter of Ryan Philippe and Witherspoon stepped out with the young gentleman in Mayfair, where they walked the streets before heading to the fabulous Sketch restaurant, which holds London's most Instagrammable tea room and loos.

She wore her blonde hair long (which she has since lopped off), with a check coat, cross-body bag, black jeans and boots, whilst he wore a grey and black ensemble.

Also 18 years-old, her potential date was none-other than Sir Paul McCartney's grandson Arthur Donald - which makes him bonafide rock royalty as far as we're concerned.

The fair looked adorable and super comfortable together on what could or could not be a date.

Donald is the son of McCartney's daughter Mary and her then husband Alistair Donald. He is currently at Yale University, despite being brought up in London, meaning the young duo may have met stateside.

There's no confirmation that this outing is anything more than a friendly meet up, but we fully ship this union.
