For the 2008–09 season, Lepailleur was joined by fellow internationals Camille Abily, Sonia Bompastor, and Élise Bussaglia.
The additions helped Paris Saint-Germain reach as high as 1st position with Lepailleur appearing in six of the first seven league matches the team contested.
On 13 March 2005, she earned her first cap with the women's national team in a match against Finland.
On 10 August 2009, she was named to the squad to participate in UEFA Women's Euro 2009, due to an injury to national team regular Sandrine Dusang.
Her mission is to continue the development and structuring of women's football within the Le Havre club [3] .
