ET caught up with Olivia Wilde at the ELLE Women in Television party on Wednesday, where the 31-year-old actress told us how she and fiancé Jason Sudeikis are living their rockstar dreams vicariously through their 1-year-old son, Otis.

"Each of us are kind of wannabe musicians, so it's as if we manifested our dreams for ourselves in this child. He just has the greatest rhythm," the Vinyl star said. "When I was pregnant, I did go to a lot of concerts. We've had music on every single day since he was born, so I don't know. I'm a big believer in reading to them all the time and playing the music all the time. It helps."

The couple welcomed Otis on April 20, 2014, 15 months after getting engaged. They have yet to announce plans for their nuptials.

While the happy family seems to be on the same page when it comes to music, sports are a different story. Sudeikis and Wilde are known to be basketball fanatics, but their son apparently needs something a little more rough-and-tumble.

"Otis, our son, is like a little meathead," Wilde admitted. "He just wants to watch football. He was very excited for the Chiefs and very sad when they lost."

The Kansas City Chiefs were knocked out of the NFL playoffs by the New England Patriots in the AFC divisional round on Jan. 16.

Prior to the ELLE Women in Television party, Wilde and Sudeikis were spotted looking madly in love at the actress' Vinyl premiere party on Jan. 15. The new HBO series, executive produced by Martin Scorsese and Mick Jagger, clues viewers into the sex and drug-addled world of the music business in 1970s New York.

Vinyl debuts Sunday, Feb. 14, at 9 p.m. ET/PT.
