POPSTARS Union J will headline Flamingo Land’s Party in the Park concert on Saturday.

The boyband will replace the original act Matt Terry - the winner of last year’s X Factor - who can no longer appear.

Union J will be joined by Stooshe, a British chart topping, Platinum selling UK girl group consisting of Alex, Karis and Courtney. They have had four top 20 hits, been nominated for a BRIT Award, have closed the MOBO’s and toured with Nick Minaj and J-Lo.

These headliners will be supported by Bailey McConnell, from Britain’s Got Talent fame, who returns to Flamingo Land after a success performance with them at a Party in the Park concert last year.

The concert starts at 6pm with a children’s Farewell Show, followed by the Spice Pirates acrobatic troupe before the two headline acts take to the stage. Tickets are on sale on the Flamingo Land website.
