Emmy Rossum of 'Shameless,' 'Mr. Robot' creator Sam Esmail announce birth of first child

Surprise! Emmy Rossum and her husband Sam Esmail are parents.

Rossum, who starred in the series "Shameless" from 2011 to 2019, took to Instagram Tuesday to announce that she and Esmail, creator of the TV series "Mr. Robot," have welcomed their first child together, a baby girl.

"On a sunny Monday morning, at 8:13AM, we welcomed our daughter into the world," Rossum wrote, captioning photos of herself with her baby bump. In the second picture, Esmail stands behind Rossum and cradles her belly as she smiles up at him. The last photo in the post appears to show their daughter's footprint.

In a separate Instagram post Tuesday, Rossum shared a photo of herself standing in a windowsill while holding her baby bump. "Two weeks before our daughter was born," she wrote in the caption.

The couple tied the knot in 2017, with Rossum wearing a custom, off-the-shoulder Carolina Herrera gown and veil for the nuptials. According to People, they wed in Central Synagogue, where they said "I do" under a floral chuppah. The celebration continued at the Guggenheim Museum.

Rossum was previously married to music executive Justin Siegel before the pair split in 2010. According to People, Rossum and Esmail dated for two years and worked on the movie "Comet" together (he directed; she starred) before getting engaged in August of 2015.
