Kate Winslet has been under the radar since announcing her third pregnancy on Tuesday, June 4. But on Tuesday, July 23, the Oscar-winning actress' baby bump was photographed for the first time while Winslet was grocery shopping near her home in Sussex, England. The star, 37, dressed her new curves in a gray, sleeveless shirt-dress. She kept the rest of her look simple, slicking back her blonde hair and slipping on flip-flops. Winslet picked up Epicure assorted cheese snacks and other items during the afternoon outing.

The Titanic actress -- already mom to daughter Mia, 12, and son Joe, 9, from two previous marriages -- is expecting her first child with husband Ned Rocknroll, whom she secretly wed in December 2012. (As previously confirmed by Us Weekly, Winslet's good friend and two-time costar Leonardo DiCaprio walked her down the aisle in upstate New York.)

Winslet was forced to hide her baby bump while shooting the upcoming movie Divergent in Chicago. "I'm holding up fine. I'm pregnant, but it's not at the point where it becomes impossible," she told USA Today while on location on Tuesday, July 16. "Sometimes you just have to roll with it."

The actress joined production after many of her costars had already begun shooting, and as such, she decided to have some fun by keeping her baby news a secret. "I wanted to break it and say, 'It's OK, I'm really fun. I promise.'" she recalled. "But I thought, just for today, I'd let them think that I am a complete bitch."
