LOS ANGELES, April 18 (UPI) -- Olivia Wilde and fiancé Jason Sudeikis are expecting their second child.
The 32-year-old actress announced the news Monday on Instagram by sharing a photo with their son Otis, who celebrates his second birthday Wednesday.
"Matching baby bumps," the Vinyl star captioned a picture of herself and Otis holding their bellies.
Wilde and Sudeikis started dating in 2011 and got engaged the next year. The couple have been vocal about wanting more children, with both Wilde and Sudeikis discussing the possibility in interviews this month.
"I'm desperate for more [kids]!" the actress told People magazine. "I love my siblings so much and Jason has incredible siblings too. The more the merrier. [Otis] loves little babies."
"Not everything [makes me want more kids]," Sudeikis said in response to E! News. "My own kid does, because I made it with Olivia and that seems like a good cocktail. I'm all for it, but not everything, no."
Wilde previously told The Daily Show motherhood is "amazing" and "so much fun" but admitted parenthood is "a balancing act." The actress plays Devon Finesta on HBO series Vinyl, which completed a first season Sunday.
Sudeikis, meanwhile, portrays Mike Miller on Fox comedy The Last Man on Earth, which airs Sundays at 9:30 p.m. ET. The actor will voice Red in the Angry Birds movie, which opens in theaters May 20.
