Rihanna has some seriously terrifying stalkers. The singer has had a couple of home intruders over the last few years, but the latest invasion of her privacy might be the scariest.

A man who goes by both Alex Mercer and Ralph Alexander on social media took a selfie outside of RiRi's house on April 30th, but the creepy trespassing stunt wasn't the half of it. The next day, the man posted a message on Twitter, tagging Rihanna and threatening violence.

"Should of killed @Rihanna a minute back I would be good right now. Sorcery is a weapon I use guns, bout to get a gun license, can’t use my hands," he wrote.

After ensuring the stalker was no longer on Rihanna's property, the LAPD have begun tracking the man through his social media accounts, phone, and computer, according to TMZ. Here's hoping they catch this guy soon.
