Hayley Williams and Taylor Swift make 'Haylor' or Harry Styles and Taylor Lautner - One Direction fans are clueless why 'HaylorIsBack' is trending on Twitter.

"#HaylorIsBack

Uhm. Have you forgotten about...

1. LARRY

2. We are never ever getting back together

and..

3. "She was a pain in the a**e," tweets @PhenomeNiall03.

Clearly, Harry Styles and One Direction fans are thinking who started this hashtag in the first place.

One fan tries to clear that 'HaylorIsBack' is Paramore's singer Hayley Williams and Taylor Swift.

"HAYLEY WILLIMAS + TAYLOR SWIFT= HAYLOR. #HaylorIsBack it's not harry and taylor. come on!!" tweets #YOUDIDITNIALL.

"@sswiftt_ffan: oh god #haylorisback harry is only using taylor for fame." LMAO literally laughed out loud bc harry is more famous then her," tweets @nfinityqueen.

It has to be seen if this hashtag is truly for Harry Styles and "Twilight" star Taylor Lautner.

Meanwhile, Harry Styles wore a black and white polka dot shirt as he took the stage with the boys from One Direction. The gig is a part of the band's "Where We Are" tour, reports Daily Mail.

Harry donned a headscarf with skulls and the rest of his attire was black as they performed at Croke Park in Dublin. Niall wore a green and white t-shirt while Liam sported a black hood, jeans, a baseball cap and Timbaland boots.

Also, Brit star Lily Allen tweeted about Harry Styles' having hair extensions. It is possible that Harry's locks may not be real suggests Metro.

Meanwhile, Taylor Lautner or Liam Hemsworth could be a part of the reboot of the "Power Rangers Movie" as Red Ranger, reports Christian Today. It looks like what started out as a speculation may become a reality. Reports suggest that Max Landis, "Chronicle" writer has been as asked to be the writer of "Power Rangers Movie."
