I can't think of anything more exciting than this next chapter and we wanted you to hear this from us first,” The Vampire Diaries star wrote in his caption . “This has been the most special time of our lives and we wanted to keep it between the three of us for as long as possible so we could enjoy this time with each other and our little one who is growing so fast...because that's what they do, they grow so fast. Thank you for your kind energy.”
