The Glee star stepped out in LA yesterday (11 December) for The Hollywood Reporter's 22nd Annual Women In Entertainment Breakfast and looked very chic stood next to her future hubby in a black and grey ensemble.
Naya, 26, teamed a black long-sleeved top with a textured grey skirt and plain black heels.
But although the colour palette was simple, her outfit was anything but boring, as the top featured a cut out section at the back and the skirt came with a peplum design to add the illusion of curves to Naya's petite figure.
Her smart look was completed with voluminous hair and big, bouncy curls.
Naya uploaded a photo of herself on the red carpet on Instagram last night and wrote: "THR power 100 breakfast #sexysecretary".
Meanwhile, the actress' rapper fiancé Big Sean colour co-ordinated with his lady by wearing a black blazer over a long black T-shirt.
This is the second time that the cute couple have been pictured looking loved up at a showbiz event in the last seven days.
On Sunday (8 December), Naya and Sean attended the 2013 Trevor Project Live in Los Angeles and couldn't stop smiling for photographers, as they piled on the PDA.
Also at yesterday's breakfast function was Sean's mentor and record label boss, Kanye West, who arrived with his fiancée Kim Kardashian and her mum Kris Jenner.
We wonder whether Naya and Kim have got together to discuss wedding details yet?
