Toscano, 26, performed at a concert which was held in the honour of Riveria, reported Contactmusic.
"I am honoured to be part of today's event which is paying tribute to an incredible fellow artist and woman. She was an inspiration and it's great that her family is continuing her legacy," Toscano said.
Singer Frankie J also performed along with Mexican singer-actress Sheyla Tadeo. Tadeo closed the night with covers of Riveria's greatest songs.
The family members of the late pop star also took the stage, including her 12-year-old son Johnny, who created a video montage of his mother.
