Former Big Brother contestants Daniele Donato and Dominic Briones dropped some exciting news on Valentine's Day: They're expecting their first child! The happy couple will welcome Baby Briones this summer.

Donato revealed the exciting baby news in a sweet Instagram post featuring a picture of her sonogram and the expected delivery date. "Happy Valentine's Day!! Hoping this year everyone's hearts are as full as mine and @dominic.phillip 's hearts ... and my belly," she wrote. "Baby Briones coming this August."

The two met while filming Big Brother 13 back in 2011 — Donato's second appearance on the show after coming in as a runner-up for Season 8 — but didn't date during their time in the BB house. That's because, while she and Briones eventually married in a bohemian-style wedding ceremony in 2013, Donato admitted that she did not experience love at first sight.

"Truth be told, I really didn't like him at first," Donato, who is the daughter of Big Brother legend "Evel Dick" Donato, told People. "I thought he was a little troublemaker. But we became friends, and although I didn't like him like that, it just grew."
