Pop star Demi Lovato says she has a crush on actress Amber Heard.
Lovato is in awe of the bisexual "Rum Diary" actress, who is engaged to Johnny Depp, and thinks she is one of the most beautiful people she has ever seen, reports contactmusic.com.
Asked who her girl crush is, she said: "I love Amber Heard. She's so gorgeous, it's ridiculous."
Lovato is a vocal campaigner for gay rights and also revealed earlier this week that her late grandfather was homosexual and came out in the 1960s.
