After getting engaged earlier this year, Big Sean and Naya Rivera heat up the red carpet in Los Angeles earlier this week for their first appearance since they made the big announcement.

The couple arrived at the Hollywood Palladium on Sunday (Dec. 8) for TrevorLive L.A., an event set to raise funds for the Trevor Project, which provides crisis intervention and suicide prevention services for lesbian, gay, bisexual and transgender youth. Jane Lynch, Rivera's 'Glee' costar, was honored at the event as a "Trevor Hero."

Rivera, who debuted the song 'Sorry,' in August, rocked a chocolate-colored Donna Karan dress and her huge engagement ring. The rapper rocked a navy blue tux with a grey bow tie. This is the celebrity pair's first public appearance together after they announced their engagement in October.

"Nothing and no one makes me happier. #hehasthebeststyle," Naya tweeted gleefully along with a picture of her leading man.
