"This sweet baby boy’s due date was today on Valentine’s Day💝 We got to meet him Monday, Feb 8th!" Trainor shared on Sunday, February 14. "We are SO IN LOVE🥰😭 Thank you @darylsabara [Daryl Sabara] for the best Valentine’s gift ever! Welcome to the world Riley!"
In the first pic, the newborn napped in a blue hat and was half-covered by a matching blue and white blanket. The next snap was a close-up of the baby’s face, followed by a photo of Trainor holding her new son in the hospital after giving birth. Trainor also shared a sweet pic of her husband bottle-feeding his son.
Fans and celeb pals flooded the comments section to congratulate the new mom.
"Riley!!!! Welcome to the world!!! Congratulations mom & dad!!" Ashley Graham wrote.
"Omg," Chelsea Briggs wrote, "congrats queen!!! He’s beautiful."
"BEST VALENTINE’S DAY GIFT FROM ABOVE EVER! So happy love you go to so much," Nicole Scherzinger gushed.
"I can’t wait to dress him up as spy kids for Halloween someday," Trainor replied to Millie Bobby Brown when the Stranger Things star asked the "Dear Future Husband" singer to teach her son all about Sabara’s role in Spy Kids.
"@meghan_trainor you are my forever Valentine and I’m so beyond grateful for you bringing our son into the world ❤️," Sabara captioned pics on his Instagram account. The actor also shared that their son was born "7lbs 8oz."
"We're so excited we couldn't sleep," Trainor gushed at the time. "We've been waiting for so long. I was thinking about who do we tell first and I've told Hoda since I was 19, going to the TODAY show, 'I will have the most babies in the world,'" she spilled. "It finally happened, and we're so excited."
