On Tuesday night, the Glee star stepped out for the Vanity Fair and FIAT Toast to Young Hollywood event in Los Angeles, California, wearing a jaw-dropping white gown that showed off her ample cleavage.
Rivera's husband, Ryan Dorsey, must have been babysitting because the new mom brought along fashion stylist, Taylor Jacobson, as her date to the party.
The cleavage-baring gown isn't the first plunging neckline Rivera has worn since welcoming her new baby. At a Golden Globes after party in January, she stepped out in a Pamella Roland gown that also flaunted her sexy curves.
While her post-baby styles are certainly scantily-clad, nothing has been quite as provocative as when she posed nude while pregnant. After posting pics from a shoot in August, Rivera had to fight off claims that she was copying her frenemy, Kim Kardashian.
"I chose to share pregnancy photos because I think this is a very beautiful and special time in my life," she Instagrammed at the time. "Media outlets know that when you give your photos and an interview to run a story you never get a choice as to when it runs. So trying to make something out of nothing based on stupid assumptions is awful. Such a shame. Especially when it comes to a woman and her beautiful pregnancy journey."
Here's a look at the nude pregnancy pics:
