Marini started her showbiz career as one of the resident singers on Ang TV, ABS-CBN's teen-oriented gag/variety show in the early 1990s. She subsequently appeared on various other television variety shows. She released her eponymous debut album in 1995 with the single "Love Song". She was included in the cast of the original soap Mula sa Puso as the lead's best friend. Her appearance in the series paved the way for Jan to play different roles in numerous drama series and specials of the two major networks. She has also appeared in several mainstream and indie films throughout her career. Jan has also performed live at music bars in the Metro. In late 2010, Jan released her sophomore album Once, containing 11 tracks, both cover versions and originals, two of which were written by Marini, including the carrier single "White Walls". Her most recent regular appearance for TV was for ABS-CBN's Pangako Sa 'Yo.
Marini took a break from years of TV work and singing engagements to build a family with fellow actor Gerard Pizarras. The couple met on the set of the ABS-CBN TV series Mula Sa Puso, where they played an onscreen couple. After dating for three years, the couple married on May 7, 2000.[1] Together they have two kids; Rian (born 2001) and Rain (born 2006).[1]
