The pair, who unexpectedly tied the knot in Cabo San Lucas in July, was spotted at Justin Timberlake's last stop for his 20/20 Experience World Tour at the Staples Center. Rivera's Glee co-stars Lea Michelle and Nolan Gerald were also at the event.
After the show, Rivera took to Instagram to share a photo taken of her and Dorsey at the event.
The actress' marriage to the Unspoken actor came three months after she ended her engagement to rapper Big Sean. Rivera and Dorsey met four years ago in LA, and the duo's friendship is said to have "blossomed into a romance" after the actress' breakup in the spring.
