One Direction have been too busy to take up an offer to appear in Glee, according to castmember Kevin Mchale.
The actor has revealed producers behind the hit musical TV show have been desperate to land a cameo appearance by the British-Irish boyband, but the singers have been unable to find time in their gruelling work schedules.
McHale tells Britain's The Sun newspaper, "We wanted them on the show badly and I thought it might happen at one time. But then they just became too big, too busy."
Previous guest stars on the show have included Britney Spears, Ricky Martin and Demi Lovato.
