Luke Macfarlane‘s Hallmark Channel co-stars are celebrating big after his announcement that he’s a new dad.

The 43-year-old actor, who filming his final movie for the network last year, revealed that he and his partner, Hig Roberts, welcomed their first baby, a daughter named Tess.

Following his announcement, Luke and Hig received a ton of congratulatory comments, and a ton of them are from Luke’s Hallmark Channel family.

The Holiday Sitter‘s Jonathan Bennett, Two Tickets to Paradise‘s Mary Margaret Humes, and Murder She Baked‘s Cameron Mathison all sent their congratulations to Luke and Hig, and so did five of Luke‘s leading co-stars.
