Real Housewives of Beverly Hills star Brandi Glanville basically threw her Twitter followers into a panic over the weekend when she informed them she had just dialed 911. So what the heck happened?

The drama started when Brandi took to Twitter to let everyone know that something was awry and had caused her to phone the police on May 19.

She tweeted on Sunday at 7:38 p.m.:

But she didn't say what was wrong, so her followers were as confused as we were. 

After being asked repeatedly on Twitter what happened, she finally responded the following day.

On Monday, May 20, Brandi clarified: 

So perhaps she heard something or saw someone in her neighborhood that made her nervous? Yikes. We're just relieved that it appears to have been a false alarm and everything seems to be fine. 

Also intriguing about this story is the fact that her ex-boyfriend came over to check on her. So who might this ex have been?

We know she recently split for good with on-again, off-again beau Jonathan Ruiz, so maybe it was him? Or was it someone else? 

Stay safe, Brandi!
