Wilmer Valderama has been in Demi Lovato's boyfriends list since 2011 and the couple is still going strong despite various rumors surrounding their relationship.

She recently told Huffington Post that she "wouldn't be alive today" if not for her TV star boyfriend and called him "a very, very good guy." They have been together on and off for five years and her 35-year-old beau reportedly helped her get through her past addiction and eating disorder.

Before Valderama, however, the "Really Don't Care" singer had relationships with other celebrities. She dated her "Camp Rock" co-star Joe Jonas for a few months.

She also tried making things work with Miley Cyrus' brother, Trace. However, their 4-year age gap and busy schedules put an end to their relationship.

According to Who's Dated Who, the "Skyscraper" hitmaker was linked to "Keeping Up With The Kardashians" star Rob Kardashian, Alex DeLeon, Cody Linley and Jonathan Fryar as well.
