Jon uploaded a photo of himself, his daughter and his girlfriend, Colleen. In the caption, he wished Colleen a happy birthday and said they had a great dinner the previous evening.
His fans were delighted that he gets to spend so much time with Hannah these days, with Instagram user Kimberley Aardse saying she's happy for him and added that Hannah looks happy too.
She also wished Colleen a happy birthday, while Katie Griggs said 'Colleen looks like a sweetheart.' Lori Schroeder wanted to know where his other children were.
Jon responded by saying it is not always possible for them to spend time with him 'when 'certain' people are involved and don't want the best for their children.'
Hannah also took to social media and shared an adorable photo collage on Instagram as a Father's Day message to Jon, who was the first one to comment!
She wrote in the caption that Jon is 'the best dad anyone could ever ask for,' and added that she loves their 'late night ice cream runs together.'
Jon replied on her post with: 'Thank you HJ love you.' Hannah has been spending more time with her father these days, leading fans to wonder if Jon has custody over the teenager.
