Chris Brown stalker who once claimed to be his ex-girlfriend was arrested at the singer's home AGAIN after sneaking in a second time on Thursday morning

Fool me once, shame on you; fool me twice, I should really invest in some better security.

A persistent stalker has been arrested at Chris Brown's home for the second time in five months.

Danielle Patti had waited outside the property until the gate opened around 3 a.m. on Thursday, before slipping inside, TMZ reported.

 However, she was apprehended by security and held until police arrived.

Brown was home at the time, but it is not known if they interacted.

Patti was charged with two counts of trespassing on Friday, and pleaded not guilty in court.

In December, she was also arrested for trespassing at his home; at the time, though, she claimed the two had hooked up, and that she was trying to leave but her vehicle was blocked in.

The singer's attorney said they are planning to file for a temporary restraining order against her.

That's exactly what she filed against him last month.

The R&B star was ordered to stay 100 yards away from the 26-year-old after she claimed he was harassing her on social media and posting death threats.

In March she appeared in court in an attempt to get a full retraining order, but failed to produce any evidence the pair had dated, as she had claimed.

After being grilled by Brown's lawyers she admitted she didn't have his phone number or his email address.

She said the reason she didn't have any of the abusive messages he supposedly sent was because she 'didn't want the memories'.
