Actress Naya Rivera, best remembered for her role in 'Glee', has gone missing. She was last seen on a boat ride with her four-year old son.

On Wednesday, Naya Rivera and her four-year-old son were boating in Lake Puru in the Los Padres National Forest in Ventura County, California. The duo had rented the boat around 1 pm, according to the Sherrif's department.

Approximately three hours passed when another boat discovered the boat Rivera was on, with only her son on it. Upon inquiring, he reportedly told the authorities that his mother went for a swim and never came back up.

The authorities mentioned that while Rivera's son was seen with a lifeguard, she didn't have any. Helicopters, divers and drones were used to conduct the search, but her traces are yet to be found. The search is going on currently.

Shortly after the news broke out, Rivera's 'Glee' co-star Harry Shum Jr. tweeted "Praying." On Instagram, Rivera had last shared a photo of her kissing her son while they were taking the boat ride.
