The Independent ?reported that 22-year-old Tomlinson bought the team together with former chairman John Ryan.
Tomlinson, one of the five members of boyband One Direction, is a lifelong fan of his hometown soccer club. Earlier this year, he played for its reserve team against Barnsley.

The takeover was twice delayed because of negotiations over image rights for Tomlinson, the Independent reported.? They have now been resolved, the paper said without details being disclosed.
The initial snag had related to Tomlinson's management team owns his image rights and argued they should get a cut of revenue, from such things as ticket sales and merchandise, generated from the use of his image or name.
The two owners have launched a crowdfunding campaign asking fans and football supporters to join him making pledges of cash to reach their funding target of £2million ($3.4 million) to support their ambitions for Doncaster Rovers (see promotional video below).
Businessman Ryan, 52, worked with the team during the time of its rise over the past 15 years before stepping down in November.
“Me and John have talked a lot about the football club, he’s a very successful business man," Tomlinson said, We have a good relationship and I think it will be a great partnership.”
