Josie Bissett is sending her best to Heather Locklear.
ET's Deidre Behar spoke with the actress as she came by the studio on Thursday to promote her upcoming guest starring role on Hallmark Channel's When Calls the Heart, where she opened up about Locklear's recent struggles with the law.
Bisset and Locklear co-starred on Melrose Place alongside Jack Wagner, who was briefly engaged to Locklear in 2011. Bisset now guest stars alongside Wagner on When Calls the Heart.
"No, no, I'm not [still in touch with Locklear]. Jack is," Bissett said. "But yeah, I just love her, she's just such a cool girl and funny and smart, and I just hope that things come around."
Locklear is facing four counts of misdemeanor battery on an officer and one charge of resisting or obstructing an officer after an incident at her home in February. A source told ET on Wednesday that the actress, who entered rehab earlier this month following her arrest, was back home and sober. Another source with knowledge of the situation, however, said that Locklear is continuing treatment at the same in-patient medical facility.
"It makes me sad," Bisset told ET of the situation. "I just, I offer her all of my support and love. I know she'll be able to get through whatever it is she's going through."
"Maybe if we do another Melrose reunion we can all get together and it'll spark a little something," she said. "I don't know."
For now, Bisset is focusing on her return to When Calls the Heart.
"[I'm] so excited, because [my character, AJ Foster] is so fun to play. She's feisty and strong and I love playing that with Jack," she gushed. "There was already this trust factor, and also similar personalities as far as sense of humor and not taking things too seriously."
"Jack and I have this ease about our relationship. It's like we always say, I just understand him, I get him, he gets me, you know?" she continued. "It's kind of like, your brother or sister, you can look at them and go, 'Oh God, I know what they're thinking right now.' It's like that."
When Calls the Heart airs Sundays at 9 p.m. ET on Hallmark Channel. See more on the show in the video below.
