Personal life

Cuthbert, who enjoys painting, is a devoted hockey fan and Los Angeles Kings season ticket holder, as are her mother and brother, Jonathan, who are active in the sport. She maintained her own blog on the NHL's web site. She began a relationship with Justin Timberlake's personal assistant, Trace Ayala, and became engaged to him in June 2004. Sometime in November 2005, Ayala remarked, "Neither one of us is in a hurry to get married." Since then, she has reportedly been dating L.A. King Sean Avery., and appeared on an MTV Cribs episode at Avery's house. The status of the engagement with Ayala remains uncertain.

Cuthbert regularly secures a place in FHM and Maxim's annual Top 100 Sexiest/Hottest lists. Her highest ranking was #5 in the 2005 UK Edition of FHM's 100 Sexiest Women in the World list. She was ranked #14 in 2003, #10 in 2004, and #22 in 2006. The U.S. Edition ranked her #53 in 2003, #63 in 2004, and #54 in 2006. She was not listed in the U.S. 2005 list. Maxim magazine named her #92 in its 2006 Hot 100 list and features her in their Girls of Maxim Gallery. As of 2006, Cuthbert has stated that she would refuse to be photographed nude in film roles or magazines, and uses body doubles whenever necessary, specifying that she "like to keep some things to [herself]".

Cuthbert has expressed an interest in returning to live in Montreal once she has reached her "higher goals" and "feel[s] content" about her career.
