The troubled star posted a photo on her Instagram Story of herself with Wagner on Saturday, Nov. 16.
The two were unexpectedly having fun getting their hair dyed together after all Locklear's recent trouble with drug abuse. Her current beau Chris Heisser was nowhere in sight.
Locklear wrote over the picture, "Look who I ran into!!"
The blonde's hair was wrapped in foil while it looked like Wagner had been working on his locks, too, as they were askew.
Locklear smirked with her arm around Wagner, flashing a thumb's up. The actor gave an open mouthed grin during their joyful day.
However, the star and Heisser recently celebrated her daughter Ava's birthday together.
Locklear, 58, and Wagner, 60, were briefly engaged in 2011, after falling in love on the set of Melrose Place. They eventually called off their nuptials for the sake of their kids.
The former Dynasty actress previously had divorced rockers Tommy Lee and Richie Sambora, the father of her daughter.
Wagner had two sons with former wife and General Hospital co-star Kristina Wagner.
As RadarOnline.com readers know, Locklear's life has been spiraling out of control for years.
Her issues began in 2008 and in May of 2019, Locklear returned to rehab for substance abuse treatment.
In August of 2019, Locklear pleaded no contest to her eight misdemeanor charges of battery and resisting officers that occurred in 2018.
To avoid two months in jail, Locklear agreed to spend 30 days in a residential treatment program. She was also placed on informal probation for three years, which means she doesn’t have to check in with a probation officer, but she cannot drink alcohol, take non-prescription medication or possess dangerous or deadly weapons.
In January 2012, a month or so after ending her engagement to Wagner, Locklear was rushed to the hospital following a 911 emergency call that came from her house. Locklear may have mixed alcohol and prescription medication but was ultimately discharged.
Wagner told ET about Locklear's recent behavior, "We all have our struggles. We all do and some of us handle them in different ways. We either really work at getting well, you know, and it’s just about when you make that decision to do it… Time will tell.”
They have clearly remained close friends and Wagner has said, "I love Heather."
