The Glee alum, who is now in the third trimester of her first pregnancy, celebrated the upcoming addition to her family with a fun baby shower on Wednesday, surrounded by her friends and loved ones.
The 28-year-old actress posted a sweet pic to Instagram showing off her elaborate baby shower cake, designed to look like the cover of the children's book Love You Forever by Robert Munsch, which was Rivera's favorite book when she was little.
Rivera, pictured with her husband Ryan Dorsey, showed off her sizable baby bump in a form-fitting black-and-white Rachel Pally dress.
Rivera and Dorsey, who tied the knot in July 2014, announced that they were expecting on Feb. 24 with an adorable Instagram post of an illustration depicting a bun in an oven.
Rivera also shared a number of cute photos of her developing baby bump over the course of her pregnancy.
