Whether it was the love of motorcycles or simply falling for the leading man, Hollywood starlet Jessica Biel expressed her passion for the latest male role in her life from the back of a Harley-Davidson motorcycle.

The former love interest of Justin Timberlake was photographed riding on the back of Gerard Butler’s Harley, cruising along the equally famous Pacific Coast Highway last week.

Although snapped enjoying some saddle time on a classic BMW in November 2010, Butler, known for his roles in 'Law-Abiding Citizen', 'Gamer' and his famous appearance in Frank Miller’s '300' has been caught more often than not on a much newer Harley-Davidson, on what appeared to be a Dyna Wide Glide.

While the brand of motorcycle may have seemed familiar to Biel, with her ex Timberlake was photographed riding around Los Angles riding one, the biker himself couldn’t have been more different.

Rumored to have struck up a friendship while filming the comedy ‘Playing the Field’ in Shreveport, Louisiana in March, Butler and Biel were out on the motorcycle last Thursday.

Although Biel is 12 years younger than Butler, the famous actor made his intentions known reportedly ‘flirting heavily’ with the recently broken-hearted actress during a movie event at a local eatery in March 2011.

‘Playing the Field’ is an upcoming film directed by Gabriele Muccino and starring Gerard Butler, Catherine Zeta-Jones, Uma Thurman, Jessica Biel and Dennis Quaid. Some would consider the movie typecasting for the leading man as Butler’s character plays a former professional athlete with a weak past tries to redeem himself by coaching his son's soccer team, only to find himself unable to resist when in scoring position with his players' restless and gorgeous moms.
