We knew the pair had met after a picture was tweeted of the two bands backstage at V Festival.
However, we admit we didn't suspect any romance!
It's believed that Leigh-Anne and Jamar get on great because they both understand each other's busy schedules and pop star lifestyle.
Now, we wouldn't let just anyone go out with our Leigh-Anne but we have proper checked this Jamar out and couldn't think of a cooler guy.
We recently interviewed Jamar and his band Cover Drive and can confirm he is loads of fun and even hotter in the flesh.
What an absolutely gorgeous couple.
So now that means that all the Little Mix ladies are taken — Jesy and Jade and dating two of the boys from Diversity while Perrie is of course dating Zayn from One Direction.
Now all we need is for Amanda to officially hook up with Niall Horan — it's going to happen, it's just a matter of time.

When we asked Amanda about it last week, she denied anything was going on but Jamar and the other Drive boys literally burst out laughing as soon as Niall's name was mentioned.
Plus, Perrie and Zayn can totally introduce her properly now if Jamar is going to be a permanent fixture in the Little Mix crew.
