"I miss this one a lot...coming home soon baby!" Adams wrote on Instagram Stories early on Saturday, alongside a photo of him with Hyland.
Hyland posted a screenshot of his post on her own feed, writing, "Man, I miss my baby."
Hyland was active on Twitter early on Thursday, responding to a joke posted by Adams.
The source told People that Adams and the actress' friends and family have been supportive and that Hyland is "looking forward to getting back to work next week."
