Demi Lovato has denied rumors that she is engaged to boyfriend Wilmer Valderrama.
The engagement rumors started doing the rounds after the 'Skyscraper' hit maker posted a photo of an engagement ring on her ring finger and wrote that she had never been happier in her life than at the very moment, Contactmusic reported.
But, the 21-year-old singer's rep has said that there is no truth behind the engagement rumours.
The couple have been dating on and off since 2010 but things became serious again in February 2013.
