Susan Boyle might be done with showtunes. The singer admitted to Digital Spy that she has quite a list of current artists she would love to collaborate with. Susan said, “There are so many people I’d like to collaborate with. Lady Gaga, Bruno Mars, Michael Buble, Adele and Kings of Leon, to name a few. I think they are such wonderful talents. I could see myself rocking it up a bit.”Boyle’s latest album is Someone to Watch Over Me.
