S Club 7 have signed a deal to reunite this summer, according to reports.
The seven-piece will be performing a series of UK gigs and one-off appearances and have lined-up a possible two-album deal, the Daily Mirror said.
A source told the newspaper: "The guys have been inundated with approaches and offers over the past three years, but always said no.
"But following a series of talks and meetings, they decided to go for it... It was a case of now or never... Everyone is really excited and frantically getting back in shape."
Rumours of a reunion for the band, who rose to fame in 1999 in the BBC series Miami 7, have been circulating for some months.
The group - Hannah Spearritt, Paul Cattermole, Jo O'Meara, Rachel Stevens, Tina Barrett, Jon Lee and Bradley McIntosh, enjoyed four UK number ones with Bring It All Back, Never Had A Dream Come True, Don't Stop Movin', and Have You Ever.
They were last seen together to support Jon's West End debut in Les Miserables in 2003.
