Actress Jackée Harry, who knew Rivera as a little girl when she appeared in her first sitcom, “The Royal Family,” from 1991 to 1992, shared her love for Rivera on Twitter.
“Prayers up for the lovely Naya Rivera,” she wrote. “We starred alongside one another in her first very television series, The Royal Family, and I’ve watched her career blossom ever since. Please God, don’t cut this life short.”
Rivera, 33, went missing on July 8 while boating with her 4-year-old son, Josey, on Lake Piru, 56 miles north-northwest of Los Angeles. A few hours after the pair rented the boat, authorities found her son sleeping alone on the vessel. The child told police that Rivera had been swimming and had not returned, according to the Ventura County Sheriff’s Department.
Josey is Rivera’s only child from her marriage to actor Ryan Dorsey. The pair divorced in 2018.
