Alexandra Daddario has revealed that she failed to hide her pregnancy from her co-stars

Actress Alexandra Daddario shared that she failed to hide her pregnancy from her co-stars.

The 38-year-old actress recently announced that she is expecting her first child with producer Andrew Pham.

"One time, I threw up outside my trailer, and my best friend had to hose it down. I was like, 'Can somebody give me a sandwich, please? And no cold cuts, please?' Ben asked, 'Are you pregnant?' And I was like, 'That's none of your business, and get me some watermelon,'" Daddario told Entertainment Weekly.

Ben Feldman, who played Daddario's on-screen love interest, recalled the actress trying to hide her pregnancy, reports Femalefirst.co.uk.

The actor, who stars alongside Harry Hamlin and Alyssa Jirels, said: "Alex has a big secret. Alex stays home every night with his secret."

Daddario announced her pregnancy earlier this month.
