It seems Tom Cruise’s biggest fan and supporter is his 17-year-old son Connor.
And Connor flew to the California set of Cruise’s sci-fi film Oblivion Wednesday, when the two were snapped chatting and smiling widely.
Connor, who’s been getting buzz as a Hollywood deejay, was also by dad’s side in Iceland when news of Holmes’s surprise divorce filing broke.
