As Andy Murray continues to hold court at the US Open, eyes are shifting to the attractive blonde on the sidelines.

Murray's girlfriend is 24-year-old Kim Sears, the daughter of tennis coach Nigel Sears. She's been spotted following Murray across the globe as she supports him during matches.

The couple has been dating for years after originally meeting at the 2005 US Open. At the time, Sears was only 17 and she was studying drama, music and art before she heading to the University of Sussex in Brighton, where she studied English literature.

Murray and Sears reportedly broke up around 2010, but their relationship has been consistently strong since, and rumor has it they may be looking to tie the knot after Wimbledon in 2013.

One thing fans know for sure about Sears is that she is passionate about pets. Not only does she run a Twitter account for her own pooch, but she's also made a successful stake in the art world by painting portraits of animals like dogs, cats and horses. Her work can be seen at her website.

Before Murray hit the US Open court, Sears supported him at the 2012 Olympic Games in London, when Murray took home the gold medal for Team Britain in the men's singles tennis competition.
