Revealing Rivera! Naya Rivera isn't afraid to flaunt her new assets. The Glee alum joked about her bigger breasts while attending the Vanity Fair Young Hollywood party on Tuesday, February 23.

"Absolutely loved this @TadashiShoji look tonight for the @VanityFair young Hollywood party!" Rivera, 29, wrote on Instagram. "Shout out to my son for the lopsided boobs. LOL #breastfeeding #momlife He is SO worth it."

Rivera wore a plunging white Tadashi Shoji dress that showed off some major cleavage for the night out. She accessorized with a diamond necklace and kept her pin-straight chestnut locks down.

As previously reported, Rivera and her actor husband, Ryan Dorsey, married in a surprise Mexico ceremony in July 2014, and welcomed their baby boy, Josey, together in September 2015. Rivera opened up about being a first-time mom during an interview with Glamour magazine at a March of Dimes Celebration of Babies event late last year. (The organization helps to raise money to fight premature births.)

"Isn't [Josey] adorable?" she gushed at the time. "Having gone through a pregnancy and becoming a mom, I know how important it is to get good health care and good prenatal care, and March of Dimes helps out with all that."

Rivera has also been posting several photos of her little one via Twitter. "Can't wait to spend what's left of my Valentine's Day with this stud," she captioned a pic on February 14. Days later, she shared a snapshot of Josey rocking aviator sunglasses. "Suns out funs out! Dolce. Converse. Stylin'," she wrote.
