The cute post comes just weeks after PEOPLE confirmed that the couple is expecting their second baby together. Usher is also dad to sons Naviyd Ely, 12, and Usher V, 13, from a previous relationship.

The star and Goicoechea welcomed their first baby, daughter Sovereign, in September.

During the red carpet for the iHeartRadio Music Awards last month, which Usher hosted, Goicoechea showed off her growing baby bump.

Ahead of the awards, the "Yeah!" singer discussed the meaning behind their baby girl's moniker in an interview with Extra.

"So, Sovereign, man, is such a beautiful word and name to me, you know, a supreme ruler is obviously the defined name," explained Usher. "She's definitely ruling the household, but Sovereign Bo - Bo is at the end of it, so [she's] my little 'reign-bo.' "

Usher introduced his daughter to the world during a virtual appearance on The Ellen DeGeneres Show last November, sharing the first photo of himself kissing the newborn's forehead.

"She looks like a little porcelain doll. She doesn't even look real," said host Ellen DeGeneres at the time, to which Usher joked, "You believe that until you have to change her diaper!"

As for Usher's sons, "they're coping well" with having a new baby sister around and are "excited about being big brothers," he added. But at the same time, "they're a little bit too protective, even with me sometimes."

"And as they get older, I'm less cool of a dad, so now I'm starting this whole cycle over again and I'm kind of the apple of [Sovereign's] eye right now," Usher said.
