While Styles may supposedly be looking to pull a Justin Timberlake and go solo, the source adds, "Harry's priority is obviously still with 1D. But when he decides the time to go solo has arrived, he's likely to have a project raring to go."
The tab also notes that Styles and bandmates Niall Horan, Zayn Malik, Liam Payne and Louis Tomlinson signed a "watertight three-album deal" with Sony, which reportedly states that "all five members will face financial consequences if one decides to quit".
On a side note, The Sun reported something similar back in January.
A source told the tab: "It's a really clever contract that the boys have signed up to. It means they have a real incentive to tough it out and stick together.
"The formal length is for 36 months and an album a year - but the clever part is they get the big pay day after the three years.
"If one of them walks away before then, then all five miss out on the money. They don't miss out on a few quid either, we are talking millions.
"They all get on really well, but it would be the kind of deal that would see them through the worst aggro possible."
But here's the rub on the Mirror's report: A spokesperson for the band says that while Styles may have been hitting the studio as a party of one, there's no solo album in the works.
"Harry is not recording solo material. All of the band are working on tracks for their third album. Harry is putting together some ideas for the record," the rep told Mail Online.
"The boys sometimes work up ideas separately as well as working together, as they did last year. Niall for example recently collaborated with Tom and Dougie from McFly on new tracks."
Styles also addressed the "going solo" rumours on Twitter.
Asked by a follower if there was any truth to the rumbles, he replied, "No not at all, I missed a recording session that's why I was in the studio in LA catching up .x".
Rumour busted.

Rivers was asked during a HuffPost Live interview last week to defend her comments.
"It's not mean. She's a chubby lady who's very, very rich, and she should just calm down - or lose weight! She wanted an apology, so I took an ad out on her a**. I said, 'You are not fat.' And then I had room for a lot of other ads," Rivers sniped.
"Adele is beautiful and successful and has what, $100 million? Let's face reality: she's fat!"
