Heather Locklear is seen without her engagement ring as she pumps gas near her home in Los Angeles

Heather Locklear’s massive diamond sparkler was noticeably absent from her ring finger as she pumped gas near her four-acre mansion in Thousand Oaks last week.

As the Melrose Place alum, 59, was seen for the first time in nearly six months for a rare outing, she rocked a green camouflage-style ensemble and black sneakers. 

While neither she or her fiancé Chris Heisser have indicated they’ve split, his most recent appearance on her Instagram was on his 59th birthday in late September.

As she filled up her car, the six-time Golden Globe nominee looked great as she wore her blonde hair in a high ponytail and a stylish brown bandana around her neck. 

Locklear rocked a subtle light gold eyeshadow, which Illuminated her sky-blue eyes, while the rest of her face was concealed under an army green face mask. 

In June, the exciting news broke that three years after rekindling her relationship with her high school sweetheart, she accepted his proposal.

She has been going steady with her on/off beau since cleaning up her act following a highly-publicized stint in rehab last August.  

The pair dated in the late 1970’s at Newbury Park High School, went through multiple marriages and have had their share of ups and downs since getting back together in the fall of 2017. 

The couple were once a item before Heather went on to marry rockers Tommy Lee from 1986-1993 and Richie Sambora from 1994-2007, with whom she has a daughter, Ava, 23.

In April, she celebrated one year of sobriety and a friend told People that Locklear ‘is in a great place.’ 

‘She is doing great and looks great,’ her pal said. ‘What’s most important is today and the next day and the future and she’s in a great place.’

Locklear marked the occasion with a thoughtful post to Instagram, in which she shared a long quote from Maya Angelou, presumably in reference to some of the things she has learned over the past 12 months.

In the caption, she wrote: ‘Hugs will come later!’ in a reference to the fact that everyone is currently self-isolating due to the coronavirus pandemic.

The quote she posted included the following: ‘I’ve learned that no matter what happens, or how bad its seems today, life does go on and and it will be better tomorrow….

‘I’ve learned that making a ‘living’ is not the same thing as making a ‘life’….. ‘I’ve learned that life sometimes gives you a second chance.

‘I’ve learned that I still have a lot to learn. I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.’   

In February 2018 she was arrested for domestic violence and for battery against a police officer who attended the incident at her mansion in Thousand Oaks, California.

In June, she was arrested again for allegedly verbally and physically abusing an ambulance EMT who responded to her home following a call for help.

Then in November 2018, she was placed on a 5150 hold after her therapist determined that she was experiencing a mental breakdown.

In August 2019, Locklear pleaded no contest to eight misdemeanor counts: five counts of battery on a peace officer, one count of battery on an emergency medical personnel, and two counts of resisting, obstructing or delaying a peace officer.

She was ordered to complete a 30-day residential rehab stay in a mental health facility with a 120-day jail sentence suspended.
