Vince Vaughn revealed Cupid got a good shot with his arrow on the set of The Dilemma.
There was a baby boom amongst the cast after filming on the comedy wrapped - Vince became a first-time dad last December, while Kevin James and Jennifer Connelly are expecting children with their respective spouses.
"Love is in the air - I'm very lucky to have my baby so I'm happy for that, I know that Jennifer is pregnant so I'm happy for her and Kevin has two wonderful little girls and there is another one on the way," said Vince.
His co-star Kevin added: "I think it was Chicago, it was just the mood. It was just everything that was happening at the time that produced it [the baby boom]."
In The Dilemma, directed by Ron Howard, Vince and Kevin play best friends whose brotherly bond hits trouble after Vince's character Ronny sees Kevin's on-screen wife Geneva (played by Winona Ryder) having an affair.
"What I connected to was the idea of how you get the information to your friend without destroying him, and in the process losing him as a friend," said Vince.
"For me, it wasn't about whether I should tell him or not. It was about watching someone burdened with the knowledge of what's going on and the struggle to figure out how and when to tell him."
:: The Dilemma is released on January 21.
