Naya Rivera's friends and costars are calling for prayers after the star disappeared during a trip to a California lake.
The Glee alum, 33, was reported missing on Wednesday after an outing to Lake Piru in Ventura County, California. Rivera and her 4-year-old son, Josey Dorsey, rented a pontoon boat and were swimming in the water.
When the boat became overdue for return after its three-hour rental, staff at the lake found it at the north side of the water with her sleeping son aboard, but not Rivera.
Reacting to news of the missing person case, several of Rivera's Glee costars asked fans for prayers that she's found soon. Heather Morris, who worked closely with Rivera on the musical comedy series, wrote on her Instagram Story: "We need all the prayers we can get to bring our Naya back home to us. We need your love and light 🙏🙏"

Harry Shum Jr., who played Mike Chang on the show, tweeted simply "Praying," as Iqbal Theba, aka Principal Figgins, wrote on Twitter, "Oh God... mercy... please..." while sharing a report of Rivera's disappearance.
Demi Lovato — who guest starred as a love interest for Rivera's Santana Lopez on Glee — wrote on her Instagram Story, "Please pray for @nayarivera to be found safe and sound," alongside a photo of a lit candle.

Had the pleasure of working with Naya and although the job wasn’t the most pleasurable, she made it so. She made me laugh on days I didn’t want to laugh, she reminded me to be appreciative of the work and the fun we were having just sitting around with each other. Praying for her, her little boy, her family...#prayfornayarivera."

Rivera's ex-fiancé Big Sean also liked a number of tweets calling for her to be found safe. The pair began dating in April 2013, becoming engaged that October. In April 2014, however, the rapper broke off the engagement, saying at the time that it was a "difficult decision."

A search-and-rescue operation was undertaken at the lake, but she was not found, according to Fillmore Police Department. Authorities suspended the search for the night, but plan to resume on Thursday morning.
"The missing person at Lake Puru has been identified as Naya Rivera, 33, of Los Angeles," the Ventura County Sheriff's Department tweeted at 10:39 pm PST. "SAR operation will continue at first light."
According to KNBC, Josey was wearing his lifejacket when he was found asleep on the boat. An adult lifejacket, believed to be the one provided to Rivera, was still on the boat. "This is considered to be a horrible accident," a Ventura County Sheriff's Department spokesperson told the outlet, adding that no foul play was suspected.
On July 2, Rivera tweeted a selfie with an optimistic message, writing at the time: "no matter the year, circumstance, or strifes everyday you're alive is a blessing. make the most of today and every day you are given. tomorrow is not promised."
