Rihanna might want to beef up her security a little bit -- two would-be robbers almost broke into her house over the weekend.
The two drove up the private road to RiRi's Pacific Palisades, California estate, walked up to the house and threw a patio chair through a glass door. But an alarm rang out, scaring them off before they could get inside. Rihanna has been in Australia and wasn't home at the time.
Despite the alarm and security cameras all over the place, police are still on the hunt for the culprits.
