The “Glee” star has given birth to a baby boy, Us Weekly reports.
She and her husband, actor Ryan Dorsey, are said to have welcomed their first child last month in Los Angeles.
"They are so excited to be first-time parents," an insider said. "Naya was born to be a mother and is doing really great so far."
And, the source added, "Ryan has amazing paternal instincts and has been waiting on them both hand and foot."
A rep for the actress did not immediately respond to the Daily News’ request for comment.
The 28-year-old star announced she was pregnant in April via Instagram.
"First comes love...then comes marriage...then comes...,” she captioned an image of a bun in an oven.
Rivera tied the knot with Dorsey three months later in a secret ceremony held in Cabo San Lucas.
The TV star has kept fans updated with a series of blog posts in which she shared the joy and challenges of being pregnant.
"With all these massive, and sometimes difficult changes happening, there is one thing about the second trimester that makes it all worthwhile: Those first real kicks from your baby," Rivera wrote in June.
"I will never forget the moment Ryan felt the baby kick for the first time. It truly was one of those precious memories I will have forever."
