She started her career as a political journalist, but soon turned towards writing for tabloids, about movie stars and other celebrities. Her first television appearance was when she became the main host of the weekend showbiz talk showMovie Magazine on GMA Network in 1987. In 1992, ABS-CBN hired Fermin to host the Sunday talk show Showbiz Lingo with Butch Francisco. Fermin's participation as main host of Showbiz Lingo had the blessings from her producers Inday Badiday, and did not run in conflict with Movie Magazine, which aired on Saturdays. But in 1994, Cristy eventually left Movie Magazine and GMA Network after she signed an exclusive talent contract with ABS-CBN, which in return capitalized on Cristy's new title as the '90s "Queen of Intrigues" by giving her the daily talk show Cristy Per Minute which started airing in 1995. Fermin also appeared in the 2003 Showbiz Gossip Series with Edu Manzano and talent manager/host Alfie Lorenzo. She also appeared in the showbiz talk show The Buzz, with main hosts Boy Abunda and Kris Aquino. Fermin was suspended by the ABS-CBN management effective October 15, 2008 until December 31, 2008, on both The Buzz and the radio programShowbiz Mismo of DZMM, due to controversial rift issues between her and former actress Nadia Montenegro. In April 2008, the Supreme Court of the Philippines affirmed a libel conviction and ordered her to pay a fine and damages to couple Anabelle Rama and Eddie Gutierrez instead of serving a jail term previously issued by a lower court. In 2010, Cristy Fermin returned on TV5 as one of the main hosts of the weekly showbiz talk show Paparazzi. She was joined by Mo Twister and former The Buzz co-host Ruffa Gutierrez. She is also a co-host of Juicy! with original hosts Alex Gonzaga and IC Mendoza. On November 8, 2010, she returned on radio when her entertainment news program, Cristy FerMinute, was launched on Radyo5 92.3 News FM. The said program is also simulcast on AksyonTV. On July 28, 2012, TV5 canceled Paparazzi, while Juicy! was canceled on August 3. Cristy began hosting Ang Latest on August 4 of the same year.
