Naya and her future husband stepped out for the 2013 Trevor Project Live, which was held at the Hollywood Palladium on Sunday (December 8) and posed for a number of fun, loved up photos on the red carpet.
Arriving hand in hand, the cute couple then switched things up a little by embracing each other in front of the photographers and even appeared to be whispering sweet nothings into one another's ear.
Naya, 26, also placed an affectionate hand on hip-hop star Big Sean (real name Sean Anderson), while proudly standing beside him in her stunning outfit.
She pulled out all the stops for her date night by flaunting her fabulous figure in a skintight brown dress that featured velvet panels down the centre.
The actress also upped the glam factor by styling her brown tresses in distinct waves and opting for golden bronze eye makeup.
Naya completed her look with a pair of strappy heels and her sparkly engagement ring.
Meanwhile, 25-year-old Sean appeared just as smitten, as he laughed and joked with his lady during their red carpet photo sesh.
He wore a super smart navy blue suit, which was teamed with a white shirt, shiny black shoes and a silver bow tie.
The showbiz couple are thought to have begun dating at the beginning of this year, after Naya followed Sean on Twitter.
They have since made a handful of loved up appearances together, including a sexy photo shoot with Terry Richardson, and Sean even featured on Naya's debut single 'Sorry', which was released in September.
Their engagement was confirmed in October.
