Naya Rivera breast surgery speculations surfaced when the brunette beauty posted an Instagram photo of her and fiancé Big Sean having fun on the beach. Clad in a black bikini, her Instagram and Facebook followers cannot help but ask whether the 'Glee' star had a boob job.

"Is this Naya or someone else? Why would you get such humongous boobs? You were gorgeous the way you were and a role model. Sad," posted Lisa Mondello Fielack

Christopher Santos believes that having money isn't an excuse to do whatever one wants: "Just because you can afford them doesn't mean you have to get them. Sad and please eat a twinkie."

 "Definitely way bigger than they were in the show. Wish women didnt feel like they had to do that to be more successful," wrote Elise Rae Bradley.

On the other hand, Ashton Colby sees nothing wrong if Rivera's chest indeed went under the knife: "Who cares if she got a boob job?! It's her body and she looks amazing btw. Don't hate."

The 27-year-old actress captioned her photo: "Beach days..." Big Sean as well as Rivera's younger brother Mychal likewise had their own Instagram photo.

Naya Rivera breast surgery has not been addressed yet by the actress. One of her recent posts is her gratitude for those who supported the hit musical series 'Glee' which would be celebrating its 100^th episode.

"Glee has and continues to be one of the most special journeys in my life," she wrote on Twitter. She also added: "Thank you to the fans, crew, producers, directors, 20th, and most importantly the cast for making these 100 episodes truly magical. Enjoy!"
