UPDATED: It’s still unclear what prompted the abrupt exit of Mark Steines as co-host of Hallmark Channel’s Home & Family lifestyle show, but now the sole host Debbie Matenopoulos addressed his departure at the end of today’s show in a statement which has left more questions than answers.

Fighting back tears, Matenopoulos, seated on a couch surrounded by Home & Family cast and crew, told viewers that Steines “is no longer with Home & Family. (You can watch the video of the entire announcement above).

“I’m here to share some news, and the family has joined me because we truly are a family and while we just had a really great show, we have a very hard announcement to deliver,” Matenopoulos said “Our dear friend, our very good friend, and my wonderful co-host for years, Mr Mark Steines is no longer with Home & Family.”

She continued, “He has been an amazing friend to all of us here at Hallmark Channel, the cast, the crew and a wonderful friend to all of you at home as well. And we are grateful to Mark, and we want to thank him from the bottom of our hearts for six of the most incredible years that he has had here hosting this incredible show that he helped build. He really did,” she emphasized. “He’s been here from the beginning and a lot of this show has Mark’s handprint on it, so we support him in everything he does in the future, his future endeavors. We will miss him dearly and we will think about him fondly and often and we thank you all at home for your kindness and understanding and your support and for being part of our family everyday.”

The show’s announcement followed a late Thursday night Tweet by the Crown Media Family Networks cable channel, saying only that Hallmark Channel had “parted ways” with Steines as co-host of Home & Family. “We are extremely grateful to Mark for his incredible work and wish him all the best success in his future endeavors,” the short statement concluded.

The channel expanded on the statement later Friday morning, “Shows evolve and change all the time,” the network said in the statement. “Mark has been an instrumental part of “Home & Family” for the past 6 years, and we are extremely grateful for his incredible work and leadership. We truly wish Mark all the best in his future endeavors.”

Deadline has reached out to Steines’ representative for comment.
