While there are many single ladies in the pop music realm, there are few eligible bachelorettes who are as desirable as Ms. Demi Lovato. Not only is she beautiful and has a fierce fashion sense, she has found success as an actress, singer and now as a reality TV show judge on the singing competition 'X Factor.' She's already dated 'See No More' singer Joe Jonas and actor Wilmer Valderrama, but who will be a suitable companion for Demi for her next relationship? We've come up with a few candidates...

First up on our list of potential boyfriends for Demi is Maroon 5 frontman Adam Levine. Even though Levine has recently been tied to model Behati Prinsloo, and he's 13 years her senior, we think Levine would still be a good match for Demi. She obviously likes older guys (Wilmer is 12 years her senior) and has a very mature yet fun-loving attitude, making the very manly yet boyishly charming Levine good boyfriend material.

Meanwhile, as Demi Lovato has experienced in the past, 'Twilight' actor Robert Pattinson is currently dealing with some serious heartache after his GF Kristen Stewart cheated on him. Demi not only knows about dealing with love troubles, but also with emotional pain in general, so she'd be able to help the very dreamy Rob through this difficult time. They'd also be a striking pair, since they are most such head-turning celebs.

Who else is on our list of potential BFs for Demi Lovato? Well, of course her self-admitted crush, the very adorable Niall Horan of One Direction, exotic 'It Will Rain' crooner Bruno Mars, 'Savages' hottie Taylor Kitsch, recently single and super handsome Wanted singer Max George, and finally, the ultra hip bespectacled 'Glee' actor Grant Gustin.

Which of these famous fellows would make a good companion for Demi? Cast your vote below!
