According to the post Tom Hanks was out for walk in Santa Monica and stumbled upon a wedding! Tom then made his way over and wanted to congratulate the couple. Then as Tom was chatting with the couple, he saw a photo of Diciembre's brother was in a chair, sadly her brother passed away. Then Tom found out that the brother and him shared the same birthday.
Diciembre then said "So he wasn't at the wedding, but Tom Hanks coming was his way of saying he was here." WOW!!!!
