Encouraged by her husband, Ferrari underwent numerous plastic surgery operations to create a 180 centimetres (71 in) silicone-enhanced bust (22 enlargements, a Guinness world record). Adopting the stage name "Lolo", from a French slang word for breasts, along with "Ferrari" as a last name, she made a few pornographic films. Use of the Ferrari name (which she justified since it was her maternal grandfather's name) led to lengthy trademark infringement court battles with the Italian Ferrari automobile company when she tried to market a line of underwear called Ferrari Underwear and a Lolo Ferrari doll. In 1995, she caused a sensation at the Cannes Film Festival with the presentation of the movie Camping Cosmos by Jan Bucquoy and producer Francis De Smet during a boxmatch which was a remake of the boxmatch in Camping Cosmos between the European champion and the former opponent of Cassius Clay (Jean-Pierre Coopman).

She used the publicity surrounding her appearance to obtain a regular role on the British Channel 4 television show Eurotrash. Ironically, when Channel 4 broadcast her obituary, it was transmitted with straight dubbing as a mark of respect. The media hype led to appearances on other European shows and work in cabaret shows doing a song and striptease act. Hoping to launch a pop music career, she recorded two singles, titled "Airbag Generation" and "Set Me Free", as well as two more singles, a Euro disco cabaret song called "Dance Dance Dance", and a cover of Thelma Houston's Euro disco hit, "Don't Leave Me This Way". Neither of the latter two songs was given a commercial release. However, Ferrari retained a cult-like following.
