One Direction are currently at odds of 1-3 to reunite this year.
The former boyband - who split for good in 2016 - could be set to make a huge comeback, according to the bookies.
The group - which consisted of Harry Styles, Zayn Malik, Niall Horan, Louis Tomlinson and Liam Payne - have been tipped to get back together this year, according to Coral.
John Hill said: "There is good and bad news for 1D fans based on these odds. We expect 1D to get back together later this year, however, Zayn is unlikely to be part of that reunion."
The firm makes it 5-4 for all five members of the group - including Zayn Malik - to appear in a reunion, while they are 2-1 to announce a new album is being made.
The five boys are still popular despite splitting seven years ago.
Harry has arguably had the most success as his solo career shot off and he is also set to appear in Hollywood film Don't Worry Darling later this year.
They have all gone on to do different things, with Liam Payne and Zayn becoming dads, and keeping out of the spotlight.
Meanwhile, Harry is making moves and headlines frequently.
His fans were left hyperventilating in recent days after a new film trailer shows the pop star in several steamy scenes.
In a teaser for Styles' upcoming film, Don't Worry Darling, the As it Was singer, in the role as Jack, performs oral sex on Florence Pugh's Alice on a dining table, and the pair are seen sharing a steamy kiss and in bed together too.
The trailer for the film, directed by Olivia Wilde, 38, sent fans of the 28-year-old superstar in a frenzy on Twitter.
One person said: "People are definitely gonna watch it for Harry styles. I give you my word."
Another wrote: "The #dontworrydarling trailer??? im SCREAMING. harry looks so good."
A third person penned: "It's the way I knew to expect this but when I actually saw it I was baffled, I did not need to see my idol give someone head."
A fourth person wrote: "Ok but Flo and H actually have me on the floor I'm not even joking like they will end me and I’m not even complaining."
