When Kate Hudson embarks on a new romance, her frequent flyer miles quickly start to pile up. While dating Alex Rodriguez, she jetted from New York to Texas to Seattle and various points in between. During her dalliance with Lance Armstrong, she cuddled with him in south of France. And in the few short months that the actress has been hot and heavy with Muse front man Matt Bellamy, she's rendezvoused with him in Paris and London. Now, they're enjoying a Hellenic holiday together. The New York Post says the rocker joined Hudson and her 6-year-old son Ryder (dad is Chris Robinson) in Greece this week. Presumably along for the getaway is Hudson's mom, Goldie Hawn, who Bellamy revealed he was set to meet this week (and feeling "nervous" about it). "Kate is really happy with Matt," a source pronounces to the paper. "Their relationship seems really natural and relaxed. It's a whole different ballgame than her relationship with Alex Rodriguez, who seemed to be more focused on himself."
