Jane Lynch - who plays coach Sue Sylvester in the musical TV show - has confirmed talks have been on-going for the 29-year-old star to take part in the show, but it has now been revealed she will be definitely be given a cameo role.
She said: ''There's been talk on set of Cheryl appearing for a year or so, but it's set to happen now. Matthew Morrison has spoken very highly of her [after she appeared in his film 'What To Expect When You're Expecting'] and the younger guys on set are keen to have her on, for obvious reasons.
''Matthew's chatted to her and she seems keen. Cheryl's the perfect 'Glee' fit, she can sing, she can dance and she looks good. It would be cool if she played herself.''
Jane also joked her alter-ego Sue would not take any messing around from the 'Call My Name' hitmaker and would be harsher on her than Simon Cowell - who famously sacked her after she worked on four auditions on the US version of 'The X Factor'.
According to the Daily Star newspaper, she added: ''She might be used to getting treated like a princess but Sue Sylvester doesn't make exceptions for anybody. If Cheryl starts acting like a diva, she'll see that Sue is meaner than Simon Cowell.''
