Her co-star Matthew Morrison put forward the suggestion and Jane said she would be 'all over it'.
She told People, 'I love that idea, and I'm all over that idea. From [Morrison's] lips to [executive producer] Ryan Murphy's ears!'
She added that her hard-nosed character Sue Sylvester would be a perfect match for Elton.
'Someone Saved My Life Tonight is probably her favourite ballad, so I don't think he would have any problem,' she added.
