The 'Wings' singer is thought to have been dating Ashford Town player Jordan since the end of last year after they were introduced by mutual friends.
But despite being together for a good few months, it seems Leigh-Anne hadn't had time to actually watch her boyfriend in action for his team… until last night.
She tweeted: "Just watching my boo play football for the first time ever! Bad gf I know! He's actually amazing.. Very proud! :) x leigh."
The singer recently threw Jordan a glam birthday party - complete with a personalised car cake - that included a night of partying at London's exclusive Rose Club. At the time she tweeted: "Happy birthday to my beautiful, amazing, gorgeous boyf Jordan! You mean everything to me, love you forever.. :) leigh x."
Leigh-Anne was seen on Tuesday night (20 August) at the One Direction movie premiere in Leicester Square, London, looking gorgeous alongside band mates Perrie and Jade Thirlwall.
No doubt they had plenty of celebrating to do afterwards as Perrie was spotted with a rather gorgeous diamond ring on her engagement finger. Sure enough, the next day her mum confirmed that Perrie is engaged to her 1D boyfriend Zayn Malik.
A rep added to Reveal: "Zayn and Perrie are engaged, but any further detail regarding their relationship is private."
