Actor Jon Paul Steuer, a 鈥90s child star best known for his roles in Star Trek: The Next Generation and Grace Under Fire, has died at the age of 33.

The members of Steuer鈥檚 band P.R.O.B.L.E.M.S. confirmed the news on Facebook on Wednesday, January 3. 鈥淚t is with heavy hearts and saddened minds that we announce the passing of our dear friend and singer Jonny Jewels, AKA Jon Paul Steuer,鈥 the band wrote. They did not disclose the cause of his death but noted that he passed on New Year鈥檚 Day, January 1.

鈥淭he addition of Jonny to our dysfunctional band family was one of the best choices that we have ever made, and he brought a much-needed sense of fun and lightheartedness to everything we did,鈥 they continued in tribute. 鈥淗e was only with us for a little more than a year, but we managed to cram a lifetime of great experiences into his tenure as our singer: dozens [of] shows at home in Portland and across several states, an amazing European tour, and our best full-length release yet. We鈥檝e lost our singer, but far, far more than that we鈥檝e lost a friend. Rest in peace, Jonny鈥e love you.鈥

Steuer was the first actor to play Worf鈥檚 son Alexander Rozhenko on TNG, appearing in an episode in 1990. An official Star Trek Twitter account also sent a tribute message in response to the actor鈥檚 death on Thursday. 鈥淩est in Peace, Jon Paul Steuer, the first actor to play Alexander in TNG,鈥 it read. 鈥淵ou will be deeply missed.鈥

From 1993 to 1996, Steuer played the son of Brett Butler鈥檚 character Grace Kelly on the hit ABC sitcom Grace Under Fire. During his time on the show, he was also cast as Johnny 鈥淰iper鈥 Vennaroin the 1994 film Little Giants. After wrapping his role on Grace Under Fire, Steuer moved away from acting to pursue music and to open the vegan restuarant Harvest at the Bindery in his home of Portland, Oregon. The restaurant is reported to have permanently closed following Steuer鈥檚 death.

Our thoughts are with Steuer鈥檚 family and friends at this time.
