MailOnline have reached out to representatives for comment.

The couple enjoyed some downtime together after Harry finished his gruelling 169-date world tour, which came to a close in July.

Taylor has also been busy, recently completing a two-month run of performances of The Effect at London’s National Theatre.

Things first appeared to be heating up between the pair, after Harry’s mum Anne came to watch the play over the summer.

Last month it was reported that Harry sees a future with the Bones and All actress, as their romance is heating up since the pair started dating over the summer.

‘Harry is head over heels for Taylor,’ a source revealed to Us Weekly, before noting that he ‘loves spending as much time with her as he can’.

The insider claimed: ‘Things are very serious, and Harry definitely sees a future with Taylor.’

Since then, the pair have been spotted enjoying various outings together as they take their romance to new heights.

‘Despite their busy schedules, they make time for each other as often as possible,’ the insider said.

More recently, the source revealed that the couple have attended ‘a number of events in London this week’.

The insider also said that the One Direction vet ‘accompanied Taylor to an after party last weekend’ for the final night of her play, The Effect, at the National Theatre.

‘Even though they’re both busy with their careers, they support one another any chance they get,’ the source told the outlet.

The happy couple were first romantically linked just months earlier when they were spotted leaving London’s White Cube art gallery together.

At the time, the pair were seen enjoying a romantic stroll through the city while holding hands.

The following month, Russell showed her support for her new beau at his Love on Tour concert tour stop in Vienna, Austria.

Shortly after, a source revealed to Us Weekly that their romance was amping up and their ‘energies work really well together’ just after ‘dating for a few months’.

The insider also revealed that ‘Harry is always smiling when he’s with her.’

Although the pair have not publicly commented on their romance, they confirmed rumours as they put on a cozy display at the press night of her play in August.

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.’
