Justin Timberlake stopped by The Ellen DeGeneres Show on Friday and couldn't help but gush about his adorable 18-month-old son, Silas. The 'Trolls' star explained that the toddler already has a knack for singing and performing, adding, "He dances around the house. He's only 18 months, I don't know, but he keeps up with all the words to 'Can't Stop the Feeling' It's kind of crazy. I feel like I'm that guy who's bragging about his kid on national television, but he's kind of rad." Timberlake went on to say, "I got to show my new movie early and he already knows all the characters. He knows like 12 characters. He's a genius, he really is."
