Jenna Leah Sanz-Agero[3] (née Piccolo; born November 10, 1969) is the former lead singer of the female rock group Vixen from 2001-2013, and a former president of Media 8.

[7] Jenna previously lead singer of local Los Angeles bands including NoNo BadDog and Belladonna, Sanz-Agero was recruited by Jan Kuehnemund to join Vixen during the Voices of Metal Tour in 2001 with other 1980s bands Slaughter, Stephen Pearcy's Ratt, and Mötley Crüe lead singer Vince Neil.

In a July 2011 interview, Sanz-Agero confirmed that a second album featuring the 2001 line-up was in the works and revealed the existence of a track called "I Understand" along with other new recordings and outtakes during the Live & Learn sessions.

Sanz-Agero amicably left Vixen and her music career in 2013, as Jan Kuehnemund was planning to reunite the classic lineup with Janet Gardner, Share Ross, and Roxy Petrucci; however, Kuehnemund died on October 10, 2013, and was replaced by a returning Gina Stile.

On January 21, 2016, Sanz-Agero appeared only for one night alongside Vixen's revamped lineup to perform with them in Anaheim, where, together, they sang "Love Is a Killer" from the band's 1990 album Rev It Up.
