"We are SO IN LOVE," the Grammy winner wrote. "Welcome to the world Riley!"
"@meghan_trainor you are my forever Valentine and I’m so beyond grateful for you bringing our son into the world," Sabara, 28, wrote.
The couple, who have been married since December 2018, both posted the same set of photos -- including snaps of them with Riley as well as some solo shots of their newborn -- but shared in a different order.
Last November, Trainor told "Good Morning America" she felt "super pregnant," "super happy" and "super blessed" and overall felt "like a super woman" during her pregnancy.

"If he changes his mind and wants to be any gender, that's great with me; that's fine," Trainor said at the time. "I just want him to be happy and live the best life."
As for what she was most excited about, Trainor said it's "having another new best friend in my life that I love so much."
