Another day and another One Direction romance rumour.

This time the rumour is that Harry’s older sister Gemma has a huge crush on Niall and Harry himself is trying to set the pair up.

Now although we’re not overly keen on new romance rumours, this is one we can definitely get on board with.

Just imagine if things went well then Niall and Harry could potentially be brothers in law.

How adorable will that be!

Anyway a source told Heat that Harry is incredibly excited about the prospect of his sister dating his band mate.

The source said: “Harry thinks Gemma’s had a crush on Niall for a while. At first, they were just mates, but as they got to know one another recently, they’ve become more relaxed in each other’s company and it seems it’s turned into her fancying him.”

There has currently been no word from Niall’s end of how he feels about Gemma, but the pair already have a special bond, even if he doesn’t actually fancy her yet.

The source added: “He’ll punch her in the arm and make jokes like they’re mates. They’re in touch all the time. Niall’s so earnest and a real trier. She loves that.”

Gemma flew over to Dublin to see the boys perform at Croke Park and while she was there, Harry introduced her to Niall’s family and she even shared a box with Niall’s Dad and brother!

If they did get together, the only potential problem we see is of they split up – things could then get awkward between Niall and Harry.

What do you think about this rumour?

Will Niall and Gemma make a cute couple?
