Yep, that was the case for young Kai Rooney who met – and snapped a load of selfies with – the 1D lads after watching their gig in Manchester over the weekend.

Mum Coleen Rooney shared the evidence of lucky Kai’s meeting with Harry, Niall and the rest of the boys on Instagram, writing: ‘Brilliant night on Saturday at @onedirection. Kai loved his selfies.’

The too-cute five year old – whose dad is Manchester United footballer Wayne Rooney – is seen making grinning with each member of One Direction, with Man United fan Harry Styles winning the prize for Most Excited Face.

Meanwhile, Louis Tomlinsonwho is expecting a child with stylist Briana Jungwirth early next year year, it was revealed in July – appeared to be getting in some dad practise as he and Kai pulled funny faces.

Coleen’s fans were quick to respond to the adorable snap, hailing Kai as ‘so cute’ and ‘a lovely boy.’

One fan even confessed the shot had brought on a case of the green eyed monster, writing: ‘This makes me laugh but also makes me completely jealous of a young child.’

But surely everyone is missing the very obvious response the photo should be prompting: Kai for the new fifth member of 1D!

And whilst Kai does his best to fill the gap left by Zayn Malik after he shocked the world by leaving the band in March, Zayn is reportedly filling the gap left by ex-girlfriend Perrie Edwards with a new lady friend.

The former 1D star shared a snap of himself with a mystery blonde two weeks ago, prompting much speculation – but the girl is now believed to be American beauty Carlyn Bryan.
