Victoria said, “Romeo, will you help with Harper’s math homework?”

He said with a straight face, “Yes, it’s actually quite simple. [The answer is] 12.’

It comes after he was seen liking the social media snaps of his model ex-girlfriend Mia Regan, 19, following their split four months ago.

For his latest post, David and Victoria’s son looked trendy in a brown bomber jacket with sunglasses – but made sure his companion’s face wasn’t visible.

Mia and Romeo split this summer after spending three years together.

But Romeo caused a stir on Tuesday afternoon after liking an Instagram post from his ex-girlfriend.

This latest update comes four months after the couple confirmed their split and Romeo deleted all traces of London-based model Mia from his Instagram.
