Los Angeles - Olivia Wilde's son is having a Beyoncé-themed second birthday party.
The 32-year-old actress' little boy Otis - who she has with fiancé Jason Sudeikis - has developed an "intense" obsession with the Formation singer, so the Vinyl star is throwing a special song-and-dance bash for when the youngster turns two next month.
She said: "Once you have a kid, their birthdays are much more fun to think about. So all I'm thinking about is Otis' birthday next month, which is number two, which is a lot more exciting than 32. That is going to be the party to be at.
"It's gonna be a Beyoncé listening party appreciation dance-off. His love for Beyoncé has really hit a fever pitch and I approve, of course, but it's intense."
