Thousands of fans were left in awe after Naya Rivera showed off her lean and sexy figure just five months after she delivered her baby.

According to ET Online, the actress gave birth to her son, Josey Hollis, on Sept. 17, 2015. It was her first child with husband Ryan Dorsey. Rivera and Dorsey, 32, got married in Cano San Lucas, Mexico in July 19, 2014, just a few months after she cancelled her engagement with rapper Big Sean.

Latina said that earlier in January, Rivera tweeted that she is a mere four pounds away from her target weight. She apparently achieved her goal by now. On Feb. 1, she shared a photo of herself at the gym with cycle instructor Nichelle Hines, which showed that she is almost back to her pre-baby body, with her tight stomach and toned abs.

“Yaaassss! Werk, It. Out. #fitmom @spingalnichelle,” Rivera captioned the image.

In an article by PEOPLE, Hines was equally proud about her client and showed this by sharing the same photo on her Instagram account. Hines wrote that Rivera’s baby is only four and a half months old.

“She eats right, rides hard and trains hard. Hard work and dedication make anything possible. What'd you do this Monday??? #bodyafterbaby #killingit #traininsane #teamnomakeup,” Hines captioned the photo. Rivera obviously took no time after her delivery to get back in shape.

PopSugar reported that the former “Glee” star let the public take a first glimpse of her adorable son during Halloween 2015. In December, she then appeared for the first time on the red carpet after giving birth at the March of Dimes Celebration of Babies luncheon in Los Angeles.

ET Online also reported that the 28-year-old actress candidly documented her pregnancy for fans. She even posed naked for a Yahoo! Photo shoot and shared some details on the challenges of having sex while pregnant, among other interesting baby anecdotes. Rivera is set to launch a revealing memoir in the spring of 2016, titled “Sorry Not Sorry: Dreams, Mistakes and Growing Up.”

According to her IMDb profile, Rivera is best known for her role as Santana Lopez in “Glee,” although she has also been in several other projects like “Devious Maids,” “The Naughty List” and “At the Devil’s Door.”

More updates and details on Naya Rivera and her diet and fitness secrets are expected soon.
