HARRY STYLES’s romance with Taylor Russell is heating up, quite literally.

The pop star has proved he is serious about the actress by whisking her off on their first couples’ getaway to the Caribbean, where temperatures have regularly been topping 30 degrees.

Harry Styles whisked his girlfriend Taylor Russell on a romantic holiday to Mustique

They have been on a romantic break on Mustique, which is a tiny private island which is popular with the rich and famous.

A source said: “Harry really likes Taylor and decided to take a holiday with her so they could spend some proper quality time together as a couple.

“She has just completed a lengthy run of shows in the play The Effect, so she finally had some downtime to spend with him.

“He loves Mustique and has been there quite a few times before. Of course the trip has been no expense spared.

“They have been staying in luxurious accommodation and taking it easy while there.”

It is no wonder they both needed a break.

Harry has been getting some well-earned rest since his 169-date tour finally ended in July, almost two years after it started.

But not long after that ended, she kicked off a two-month run of daily performances of The Effect at London’s National Theatre.

It was first revealed that they were an item back in June and she has since met Harry’s mum Anne, who came to see her in the play.

Speaking back in August, Taylor, who has also starred in the film Bones And All and the sci-fi series Lost In Space, shared her feelings on relationships and said she always expects to be left bruised by love.

She explained: “You are going to be hurt – that’s the tax. The tax on a real relationship is the reality that you will get hurt, you will [have] grief, something will be lost at some point and that’s OK. It’s worth it.”

But she said that she finds love intoxicating.

Taylor added: “What’s my favourite drug? Does love count? I mean, love, a lot of the time, feels like a drug, you feel so insane.”
