UPDATE: Law enforcement sources tell TMZ Heather had taken a combination of prescription drugs and alcohol and her sister believed she was in danger. After the call was placed and paramedics arrived, they examined her and determined she needed to be hospitalized.
Someone in Heather Locklear's home just made a 911 call today, fearing that Locklear was psychologically unstable and might do something drastic to herself.
"The person who made the call was worried about Heather's state of mind and they were afraid that she was going to harm herself," a source tells RadarOnline.com.
This call happened just a few hours ago, and now TMZ is reporting that Locklear has been rushed to the hospital and that the person who made the emergency call was her sister. The fire department responded to the call and showed up at Locklear's Westlake home.
The RadarOnline source says that Locklear hasn't been in her right state of mind since calling off her engagement to Jack Wagner back in November, 2011.
"She is distraught over her relationship with Jack, it is on and off and it has upset her lately," says the source.
Her sister was seriously worried about Locklear's well-being and was afraid she would do something to hurt herself.
This isn't the first time this has happened to the actress. Back in 2008, someone who claimed to be her doctor made a 911 call that Locklear was trying to commit suicide at her home. However, like this time, when the police arrived everything seemed to be fine and they left.
Locklear has been to rehab during the summer of 2008 for psychological issues related to anxiety and depression. Hopefully, for her sake, this doesn't happen again.
