Joubert has been considered a heartthrob in his native country, France. This reputation has been contributed by media appearances after his first victory at the 2004 European Championships and silver medal at the World Championships and short relationship with former Miss France, Lætitia Bléger. He later brought a lawsuit against Bléger for 40,000 Euros for insinuating that he was homosexual and that their relationship was arranged to hide this. Bléger and two magazines that published her allegations were ordered by a French court to pay a total of 17,000 Euros, and to publish the court ruling in one of the two magazines. Joubert was later involved with Italian figure skater Valentina Marchei but the relationship ended by 2009.
