While at yesterday's BAFTA Los Angeles Brittania Awards, the 50–year-old told UsMagazine.com:
'But I can't say who but you may know who it is!
'I'm really excited about the wedding, we shot it already and it was so much fun!'
Jane also raved about Gwyneth Paltrow, who guest stars in an upcoming episode of the musical-comedy.
She added: 'I did a couple of scenes with her, and she is awesome.
'There is nothing she can't do - she sings, she dances, she acts, she is funny and a great mum and a good person!'
