This is so scary!

Lisa Rinna revealed Wednesday that she was the victim of a terrifying kidnapping hoax, in which she received a phone call from someone who claimed to have her daughters in their possession. The stranger threatened to kill her children unless the reality star forked over an undisclosed amount of money.

The good news? The Real Housewives of Beverly Hills star's kids Delilah and Amelia were perfectly safe, and the scary incident is a scam that is now being investigated by the FBI.

"They put a child crying on the phone saying mom help me please and then they try and extort money and say they will kill your child. It is the worst scariest nightmare and it must stop," the TV star wrote in a tweet, which has since been deleted.

"I took those posts down because they freaked my daughter out too much. Those of you who saw them it was a very real scam. Be aware," she explained.

We're glad everyone is OK!
