Naya Rivera stunned at the star-studded The Hangover Part 3 premiere at The Village Theatre in Westwood, Calif. on Monday.

The actress showed off her toned abs in a black crop top and high-waisted sequin pencil skirt. The Glee star impressed in the Donna Karan ensemble. Her new boyfriend, Big Sean, walked the red carpet with the actress on her big night.

The couple was first seen in public together in April on the red carpet for the premiere of 42. The 26-year-old actress and 25-year-old rapper were rumored to be dating since earlier this year. Rivera was also spotted attending Big Sean's birthday party in March.

Rivera, evidently confident in her physique, posed nude for Allure magazine in April. 

The entire Hangover 3 cast was present for the film's premiere on Monday.

Co-star Heather Graham also dressed to impress in a Herve L. Leroux teal gown. Bradley Cooper, Zach Galifianakis, Ken Jeong, Ed Helms and Justin Bartha all took non-traditional approaches to suiting up for their premiere.

The Hangover 3 reunited director Todd Phillips with leading men  Cooper, Helms and Galifianakis (along with several other returning cast members from the two previous films). The Hangover premiered in theaters in 2009 and grossed more than $467 million. Two years later, The Hangover 2 brought in even more at the box office with $586 million. 

Before the sequel was released, Philips said he intended for the comedy film series to be a trilogy.

The film opens in theaters Friday, May 24.
