“Our little koala bear was born at home at 8:54am. She’s divine and smells like bubble gum and roses. We’re all obsessed,” Jonas wrote on Instagram along with a photo of their newborn.
“Rome Coco Thompson. September 20, 2017 Welcome to earth,” Thompson, 40, said.
And on Wednesday, the proud parents celebrated Rome Coco turning 1-week-old.
“Morning snuggles forever please Miss Coco,” Jonas wrote.
The couple is already parents to 16-month-old Bowie Banjo.
“I love being a dad, and we’re really looking forward to bringing a girl into our little family,” Thompson said about expanding his family.
Aside from his newer turn on The Young and the Restless — he joined the cast as Billy Abbott in early 2016 — Thompson is best known for his longtime role as Dr. Patrick Drake on General Hospital, which he played for over a decade beginning in 2005.
