Justin Timberlake is a proud father first and foremost!

The 35-year-old superstar stopped by The Ellen DeGeneres Show to tape an episode airing Friday, where he opened up about his 1-year-old son, Silas. Timberlake says the musically inclined Silas dances around the house, and is super smart for his age.

"He keeps up with all the words to 'Can't Stop the Feeling,' it's kind of crazy," the Trolls star shared. "I feel like I'm that guy who's just bragging about his kid on national TV. But, he's pretty rad."

"He's kind of smart," he continued with a laugh. "He’s kind of smart, you guys. He didn't get that from me."

Not surprisingly, Silas is a big fan of his dad's new animated film, Trolls.

"One of the perks of doing this film was that I got to screen it early for my son, and he already knows all the characters," he marveled. "He knows, like, 12 different characters. He's a genius, he really is."

As for when his fans can expect new music from him, Timberlake remains tight-lipped. But he does confirm that he's been in the studio with A-list hit-makers Pharrell Williams, Timberland, and Max Martin.

"I've always been this way, you know," the GRAMMY winner noted about not nailing down any specific release date. "I just don't know until it's done. You want it to be right. You want it to be something you love."

ET spoke to Timberlake last month, when he told us about how Silas adorably recognizes his character in Trolls. "I got to screen it before anybody. I had to screen it before everybody because I had to make sure all the music was working out," Timberlake said, explaining how Silas, whom he shares with wife Jessica Biel, was already able to fall in love with the film.
