Did "Glee" beauty Naya Rivera secretly get a boob job?

Rivera posted a VERY sexy bikini photo on Instagram the other day, while hanging-out on the beach with rapper fiance Big Sean:

nayarivera: "Beach days..." 

The 27-year-old actress looks great - and a little busty! Especially compared to older (yet still recent) photos...

Now, several fans and gossip tabloids are left wondering if Rivera got a major breast enhancement. Here's another Instagram snapshot:

nayarivera: "Love my look tonight! Thank you bec and bridge!"

Rivera has yet to respond to the boob job rumors - instead, she remained focused on celebrating the 100th episode of "Glee" (which aired on Tuesday night, March 18):

@NayaRivera: "'Being a part of something special makes you special.' Glee has and continues to be one of the most special journeys in my life."

@NayaRivera: "Thank you to the fans, crew, producers, directors, 20th, and most importantly the cast for making these 100 episodes truly magical. Enjoy!"

Do Mstars readers think Rivera went under the knife to enhance her figure? Either way, Big Sean seems very pleased with his future wife's figure!
