Just a few days ago, she was seen filming more Modern Family scenes wearing a prosthetic baby bump as her pregnant character Gloria

But Sofia Vergara went mysteriously without it today as she shot more of the sitcom in Los Angeles.

The 40-year-old actress looked lovely in a white strapless lace dress and wide brimmed hat as she chatted to co-stars and sipped on juice between scenes.

The white stuff: Sofia Vergara looked pretty as a picture in a lacy sun dress and hat, without her prosthetic baby bump on the set of Modern Family in Los Angeles on Monday

The star teamed her outfit with some towering leopardskin platform heels and crimson lipstick, and wore her long hair in loose waves.

Without her fake bump, the star was able to show off her enviably slim figure.

Just a few days ago, the actress was spotted sporting the baby bump as she and the cast filmed a baseball game in the Los Feliz area of Los Angeles.

Sporting a faux baby bump, the actress took centre stage at the children’s sports event as she sung the American National Anthem.

As the Spanish-speaking personality belted out The Star-Spangled Banner, she looked glamorous in black leggings and leather boots which she wore with a colourful top featuring animal print design.

But she seemed to be quite active considering she is meant to be portraying a heavily pregnant woman.

She pranced around on the grass to stake out her spot before opening her mouth widely to sing as she passionately swung one arm up into the air.

Stood in the background for the scene were players holding their caps to their chest in respect of the tune.

Meanwhile her co-stars Ty Burrell, Eric Stonestreet, Julie Bowen and Jesse Tyler Ferguson enjoyed acting as support from the sidelines.

Later on, Ty’s character Phil Dunphy could be seen jumping high as he donned jeans and a shirt to play on the defending team.

Eric – who plays Cameron Tucker on the show – was pictured wheeling a kart around on the lawn.

Jesse’s character, Mitchell Pritchett, was joined by his on-screen adopted daughter and Burrell as they carried around bunches of flowers.
