Days after celebrating her 25th birthday in Hawaii, Rihanna had an intruder at her home in the Pacific Palisades.

TMZ reports that the suspect was on Rihanna’s property and actually spent time inside her mansion.

When arrested, he told police that he had received instructions on how to invade Rihanna’s home via email. Neighbors noticed him on the property and called the cops once they questioned him and realized he did not belong at Rihanna’s home.

It is unclear whether or not the intruder stole anything.

Meanwhile, earlier this week, Rihanna spent her birthday in Hawaii -- with boyfriend Chris Brown.

She posted a photo with her on-again beau, along with the caption “Pour it up pour it up! #birthdaybehavior.”

Just days ago, it was reported that Rihanna and Brown had allegedly broken up over text messages she sent to rapper Drake.

“Chris and Rihanna had a big bust-up at the Grammys over Drake," a source told the Sun. "She was messaging him, and Chris saw, and it didn’t go down well. Since that night, they have barely spoken and have been doing their own things. For now, they have split up, but they will probably make up at some point.”

Drake and Rihanna are rumored to have had a brief fling before going their separate ways last year.

But it seems Rihanna and Brown are still going strong.

The couple dated for two years before the relationship ended violently, when Brown attacked Rihanna while driving in 2009.

But back in February, Rihanna was featured on the cover of Rolling Stone magazine and admitted that she being with Brown fulfills her.

"I decided it was more important for me to be happy, and I wasn't going to let anybody's opinion get in the way of that,” she said.
