The baby on the way will be Simpson Ross' third child and her second with husband Evan Ross. She shares daughter Jagger Snow, who turns 5 this month, with Ross, plus 11-year-old son Bronx Mowgli with ex-husband Pete Wentz.

"We are pregnant and we are so excited to share it with everyone. Baby #3," Simpson Ross captioned her post, while her husband wrote alongside his, "The fam is growing. ♥️ Ash and I can't wait to welcome the newest addition."

"During this unprecedented time, we know pregnant women may be under greater stress which is why we are supporting @marchofdimes Mom and Baby #COVID19 Intervention and Support Fund," the mom-to-be added, referencing the ongoing novel coronavirus pandemic. "Check out their Instagram page to see how they are helping moms and babies get the care they need now and in the future."

The following month, Jagger and Bronx helped their parents reveal the baby's sex, cutting into a cake filled with blue sprinkles to spill the exciting news to Simpson Ross' Instagram followers.

In the clip, the family members held a knife together as they sliced open a confection made by Los Angeles bakery Cakes by Claritza. When blue sprinkles poured out from the cake, Simpson Ross excitedly announced that she was having a boy before giving her daughter a hug.

"💙💙💙🙏🏼💙💙💙," she captioned the video.

Meanwhile, the dad-to-be — who is the son of Diana Ross — shared the same footage on his Instagram account and wrote, "SO STOKED 2 MEET MY BABY BOY 🖤 as u can tell Jagger wanted a sis 😂."
