Taylor Swift fans have been left convinced ex Harry Styles will join her stage for the latest gig of her sell out Eras Tour at Wembley on Monday.

The American songstress, 34, reportedly enjoyed a three month fling with the former One Director star, 30, between 2012 and 2013 before splitting following an ‘almighty row’.

On Sunday, after Harry was spotted strolling through London with Taylor’s close friends and singing sisters Este, Danielle and Alana Haim, Swifties were sure this meant he was also in contact with the Bad Blood hitmaker.

After the footage was posted on X, fans commented: ‘Next notification we’re about to get is set for tomorrow and it’s Harry Styles and Haim spotted at the eras tour at Wembley’: ‘And ur gonna hate me for saying this… but harry hanging out with the Haim sisters means theres about a 98% chance he’s also hanging out with Taylor’.

While someone else shared a snap of another ex Taylor Lautner on stage, proving the singer has a history of bringing out former flames during gigs.

Little more than a week after a very public display of affection on new year’s eve as the clock struck midnight to kick off 2013, a source confirmed to MailOnline that Harry and Taylor had parted ways.

The source said: ‘Yes I can confirm they have split up. They were on holiday and had an almighty row. They are two young stars at the top of their game so who knows what will happen in the future.’

Taylor, who is known to write songs about past relationships, is thought to have penned at least three songs about Harry- I Knew You Were Trouble, Style and Out of The Woods.

In 2015, the singer revealed her whirlwind romance with Harry had been an experience filled with anxiety.

During a performance at the Grammy Museum, she introduced Out of the Woods by telling the audience about her anxiety-inducing relationship – although she didn’t mention Harry by name.

‘I’m going to play you a song that I wrote about a relationship that I was in that the number one feeling I felt in the whole relationship was anxiety,’ she explained as she sat at her piano.

‘Because it felt very fragile, it felt very tentative. And it always felt like, “Okay, what’s the next road block? What’s the next thing that’s gonna deter this? How long do we have before this turns into just an awful mess and we break up? Is it a month? Is it three days?”‘

It comes after the singer’s fan’s latest theories about her Wembley shows proved to be less true than they’d hoped, as Post Malone failed to make an appearance during the third show on Saturday.

Swifties had been left convinced that Malone would take to the stage with the hitmaker in the capital, after noticing a key detail on the poster for the shows.

The billionaire songstress is in the middle of the second leg of her Eras Tour with five shows at the London stadium, following her string of sell out dates there in June.

However, as Taylor took to the stage to perform Fortnight, from her newest album The Tortured Poets Department, Malone was noticeably absent.

Eagle-eyed fans had been led to believe the rapper would join her on stage after noticing symbols next to each concert date on promotion for the show.

The poster featured a typewriter – a symbol which appeared heavily in their music video together – next to Friday’s gig.

Fans were left even more convinced of their theory after Taylor shared a snap of her and Malone, real name Austin Richard Post, to her Instagram Stories shortly before showtime.

In a gushing tribute she wrote: ‘Was lucky enough to hear this amazing music on set of the ‘Fortnight’ video when Austin played it for me.

‘It’s incredible how versatile his artistry is. And just the most down to earth guy alive’.

On the poster, her first concert date included a heart, which fans believed was hinting the surprise appearance of her beloved pal Ed Sheeran, 33, who sent the crowd wild when he walked out on stage.

Thursday’s the featured star, which Swifties have concluded was in reference to the debut of her new Midnight bodysuit.

Looking ahead they concluded Monday, which had a top hat symbol, would see Taylor’s boyfriend Travis Kelcee, 34, return to the Wembley.

Last month the American Footballer, dressed in a top hat and tails, took to the arena stage during one segment as he helped his girlfriend with a costume change.

Then the final gig includes a camera, which was interpreted as the announcement of a behind the scenes documentary of the tour.

After one fan posted the theory on X, other raced to the comments convinced they’d cracked the code, writing: ‘Also the fact that when Travis was on stage [Taylor] said it was his “debut” which leaves me thinking it was definitely NOT his last time on stage’: ‘ Okay you’re onto something’: THESE ARE WHAT I WAS THINKING EARLIER TOO!!!!’: ‘Definitely Post Malone! Taylor’s private jet flew yesterday from Nashville to London…and Post was in Nashville all week!’

However others were quick to pour cold water on the idea, pointing out it was likely in reference to her support acts and the fact that Post was busy promoting his new album in Nashville while Travis was training with his team the Kansas Chiefs.
