Although Patrick Schwarzenegger has vehemently denied cheating on Miley Cyrus while on spring break, the 21-year-old has now found himself the victim of some scary death threats.

Miley's fans are not happy with Patrick, and after the singer posted a series of cryptic tweets -- one NSFW -- about self-esteem and friendship, they have been sending the young actor some troubling tweets.

Miley Cyrus has kept quiet since her Instagramming spree, but Patrick's 25-year-old sister has come out in defense of her younger brother, tweeting "A lot of you guys spreading hate need Jesus in your lives ASAP."

After pictures surfaced of Patrick hugging a bikini clad woman in Cabo, he has continuously maintained his innocence, tweeting, "Omg. It's one of my best friends girlfriend...Would NEVER do anything against my GF.....," he tweeted on Monday. "Girls have guy friends and guys have friends that are girls..."

The couple has reportedly been dating since November of last year, and appeared recently to be getting serious. In January, the couple took a sexy topless beach vacation in Hawaii.
