Lamar Sally told PEOPLE that he's lost "freakin' 50 pounds" as he goes through the process of separating from his wife, actress and The View regular Sherri Shepherd.
"Use a slim picture," he joked. "Not the fat one from six months ago … I'm on the divorce diet."
Sally declined any further comment on his divorce from Shepherd, but added, "I'm happy to be a father."
Sally and Shepherd filed for legal separation on May 2, with the papers also revealing they are expecting a baby boy on July 28 – and that Sally wants full legal and physical custody of the baby.
News of their split reportedly even came as a surprise to those close to Shepherd.
"It seemed like they had a happy, supportive relationship," a source close to Shepherd told PEOPLE.
