Heather Locklear was reportedly taken by ambulance from her home in Thousand Oaks, California, to a nearby medical facility, with emergency responders also requesting back-up from the Sheriff's Department after receiving a call to say the 56-year-old star had overdosed.
Sources told TMZ that Heather is in a stable condition and receiving treatment.
Heather was said to have been planning to check herself in for treatment but seemingly overdosed just hours after she was bailed out of jail following her arrest on Sunday evening.

Heather was initially taken to hospital to receive treatment, and she was later taken to jail, where she was held on $20,000 bail.
