In July 2005, Pauline had a serious accident while playing on a trampoline, where she fell on her head. It turns out that she was not seriously injured; only suffering a dislocated shoulder.
Like her siblings, she is active in social networking sites like Facebook and Twitter. When she was in Singapore for the 2010 Youth Olympics, she even tweeted from her phone! She is a fan of Michael Jackson, the movies Grease, Sex & the City 2, and A Cinderella Story, and the television show Desperate Housewives. Pauline has nearly 1000 friends on Facebook, among them are her three siblings Michael, Louis and Camille, paternal cousins William and Estelle, maternal cousin Jazmin Grace and ex-stepfather Adans Peres, several of her friends from the Youth Olympics-Hannah Thek, Pamela Ware, Liu Jiao, Fanny Bouvet, Kieu Duong, Elena Bertocchi, Teresa Vallejo, Beannelys Velasquez and fellow Moneguse atheletes Amélie Trinquier, and Christopher Déléage.
In 2010 she represented Monaco at the first ever Youth Olympic Games in Singapore, where she participated in diving. At that competition, Pauline made to the finals in 9Th position, and ended up 12th out of 13 divers over all (12 girls made it to the finals). In 2009, she represented Monaco at the European Junior Swimming Championships in Helsinki, Finland where she placed 19th and 22nd. At the 18th FINA Junior Diving World Championships in Tucson, Arizona, USA in 2011, she placed 21st and 29th. On 5 November 2010, Pauline was nominated as "Sportsperson of the year" for the 2009-2010 season. She did not receive the honor, however, just for being nominated, she received a gold trophy. Pauline also participated in the World Junior Diving Championships in Aachen, Germany. She participated in two diving schools in recent years-one in Strasbourg, France and another at the University of Indiana. She has also expressed interest in participating in the Olympics someday.
