The "Baby Daddy" star, who appeared alongside McEntire on sitcom "Reba" for six seasons, gave an update on the 60-year-old country superstar to ET at ABC's all-star summer TCA party on Tuesday.
“I’ve talked to her and she’s doing great,” Peterman, who was with her "Baby Daddy" co-stars on the carpet, told ET.
“Beyond what she said in her statement, I love her and I wish her all my love, and that’s all I can say right now,” the 44-year-old actress said of her good friend. “I love her.”
“We love you Reba!” Peterman’s "Baby Daddy" co-star Chelsea Kane added.
The pals will reunite once again on the small screen when McEntire returns for the season four finale of ABC Family’s "Baby Daddy" on Wednesday.
On Aug. 3, McEntire and Blackstock announced in a joint statement on her website that they were splitting up.
"Despite this being the end of their marriage, they continue to support each other," the statement read. "They have worked together for 35 years and will continue to do so. They have asked that you respect their privacy during this time."
The pair have a son together, Shelby, a race car driver. Blackstock has three children from a previous relationship, including son Brandon, who is married to singer Kelly Clarkson.
