'Glee' has made room for a pretty impressive range of guest stars, including Gwyneth Paltrow, Britney Spears, and Lindsay Lohan -- and according to star Matthew Morrison, Adele would be a natural addition to the list.

"I'd love to see Adele," revealed Morrison during a red carpet interview at the U.K. premiere of 'What to Expect When You're Expecting.' Morrison added, "I don't think she should sing on the show," conceding, "I don't know what she would do, but it would be fun to have her on the show!"

Later, asked about the potential for his 'Expecting' co-star Cheryl Cole to make a guest appearance on 'Glee,' Morrison admitted, "I think they all know who she is, so I think that it's up to them. I will lobby for people that I really want on the show but I haven't done that for her. But there's so many people that want be on that show!"

Continued Morrison, "Coming to London a lot, you can't get away from her or go without seeing a picture of her so it was great to finally interact with her as a human being, it was fun. I think she's a beautiful woman ... but I'm taken!"
