Whenever we see the children of celebrities publicly celebrate their parents, it warms our hearts — and the latest example is no exception: John Travolta turned 67 on Thursday, and to mark his latest trip around the sun, his daughter Ella Bleu posted a sweet birthday tribute on her Instagram that has us feeling so emotional. Travolta has always been a very loving father to his kids, Ella and Benjamin, on social media, and seeing Ella honor her father makes us so happy.
