Jessica Biel and Justin Timberlake's son Silas could follow in his father's musical footsteps.

The couple welcomed Silas in April, 2015 and he is already showing signs of musical talent, just like his father. The tot constantly plays the drums and piano at a "genius level", gushes hit doting mum.

"(He's) very musical," a proud Jessica tells U.S. chat show host Ellen DeGeneres. "He's really, really in love with Erykah Badu. He loves her music. He eats to her music.

"He's got just recently these drum sets. He likes to drum; he likes to play with his piano. And he likes to drum with his head… which I just think that's genius, if you ask me. That's genius level."

Silas' exposure to music began when he was still inside Jessica as she attended many of Justin's concerts during his 20/20 Experience World Tour while pregnant.

"I went to probably 40, 50 concerts when I was pregnant, just stood there and the music was just slamming. I actually thought, 'I'm going to damage this child'... not yet!" she joked.

The 34-year-old teased she was expecting baby number two by replying, "I know, isn't it exciting guys?" when Ellen questions her on the pregnancy reports. The actress then brushed off the news by remarking she can't be working out enough.

“I don’t even know what to say about these things", she adds. "I feel like, man, I thought I was doing good with my yoga practice. I thought I was in the gym, but no, I have a gut apparently."

During the interview, which airs on Thursday (24Mar16), Jessica gushed about her husband's music and called herself his number one fan.

"I listen to his music probably more than I should. It’s maybe slightly creepy. I love his music... Silas loves his music so I want him to hear it a lot. We listen to it in the car a lot... " she explains.

Jessica and Justin, who married in 2012, are gearing up to celebrate Silas' first birthday in April (16).
