We’re sad to report that Twilight actor Gregory Tyree Boyce and his girlfriend Natalie Adepoju were found dead in their Las Vegas condo last week.

According to E! News, Gregory and Natalie’s cause of death is pending a toxicology report.

Gregory was known for his role in the first Twilight movie, where he played Tyler Crowley, a character who has a crush on Kristen Stewart’s Bella Swan.

His mother posted a tribute on Facebook calling him “the best chef,” adding, “I’m sick without you. I’m torn, I’m lost. I’m in pain.”

According to a source at E!, Gregory had moved to Las Vegas to care for his mother, but “would commute to Los Angeles for acting jobs and to see his daughter.”

We’ll be following this story. Our hearts go out to their families.
