Britney Spears new romance with her manager has added to the circus that is her life (and her current world tour), but the relationship is apparently not playing along the lines of her previous ones, people close to the couple have told ABC News.com.
Sources say Jason Trawick, 37, has taught Spears that she can't get away with her usual boy-toy domination.
He is, after all, her manager -- her last serious relationship was with ex-husband and father of her two children, Kevin Federline, who sashayed into her life as her backup dancer in 2004. After their divorce, she was frequently seen with Adnan Ghalib, a paparazzo who went from snapping Spears to accompanying her on shopping sprees.
"Jason's a successful businessman who's used to giving advice to Britney, not listening to personal demands," a source close to Spears, 27, told ABCNews.com. "He doesn't worry about her every request."
Trawick's relationship with Spears evolved from strictly business to something more months ago. On March 1, paparazzi spotted Trawick in Louisiana riding a golf cart with Spears and her sons, Sean Preston and Jayden James.
In May 2008, Trawick flew down to Costa Rica with Spears and Mel Gibson for a getaway at the actor's tropical mansion. Photographers snapped pictures of Trawick and Spears frolicking in the ocean and cruising on ATVs.
Trawick is said to have a warm personality and professional drive -- in addition to repping Spears for the past five years, he also serves as an agent to Hilary Duff, Taylor Swift and Paris Hilton -- and that may have made Spears see him as a potential partner.
