Olivia Wilde is expecting a baby boy.
The 29-year-old actress - who is six months pregnant with her first child with fiancé Jason Sudeikis - let the tot's gender slip as she revealed he is extremely active during the 71st Annual Golden Globes on Sunday (12.01.14).
She said: "He was kicking the whole time, going, 'Where are we?!'"
The blonde beauty - who had covered her bump in a sparkling Valentino gown for the ceremony - is embracing her pregnancy curves.
She said: "It's great I've never had boobs before!"
And the 'In Time' star admitted she is glad her bump is becoming more prominent.
She told People magazine: "Until about a week ago, I just looked fat! I wanted to be like, 'I'm not fat, I'm pregnant!' "
While Olivia loved the green gown she donned for the awards, not everyone was a fan.
She tweeted: "I just heard someone say I looked like a giant, walking pickle last night at the Globes. As a pickle enthusiast, I thank you."
