Sherri Saum celebrated the upcoming arrival of her twin boys at a baby shower this past weekend with some of her co-stars on " The Fosters."

"This was an amazing day with friends and family," Saum told ABC News. "These boys are going to be surrounded by love!"

Saum's mother hosted the shower in the garden of the 39-year-old actress' Hollywood Hills home, which was decked out with a cheerful display of onesies strung across the trees. The catered menu included sandwiches and RealBeanz iced coffee beverages.

Guests took home mini baby bottles filled with blue and green jelly bellies.

Among the 35 guests who attended was Teri Polo, who plays Saum's wife in the ABC Family TV series about two moms in a same-sex couple raising a mix of biological, adopted and foster children. Saum's co-stars Maia Mitchell and Madisen Beaty were also on hand to help her celebrate, as well as Saum's former "One Life to Live" co-star and "Brooklyn Nine-Nine" actress Melissa Fumero.

Saum told People magazine in February that she was expecting twin boys with her husband, "One Life to Live" star Kamar de los Reyes, after her "Fosters" co-star Danny Nucci outed the babies' gender during the Television Critics Association press tour in January.

"It's a good place to out it though - they're boys!" the former "In Treatment" star told People.

Saum also posted a photo of herself sporting two blue bows on her belly, along with the message, "Boy oh boy… Happy Monday!"

The first-time parents, married since 2007, appear unfazed about taking on twins.

"Chaos will reign," Saum told People. "We're just going to take each day as it comes. [They're] my first children, so I'm not going to know anything different. It's going to be easy and breezy."
