I'm with Her (2003)

On the day that would change his life, delightful young everyman Patrick Owen is drinking his mid-morning latte when he's bitten by love. Literally. The gnashing jaws belong to Monroe, the easily-excited puppy of movie star Alexandra Young. When she tries to apologize and when Patrick recognizes her famous face he's awestruck, dumbstruck, and so very charming. Alex sets her sights on Patrick, but he's unprepared for the add-ons that come with this little flirtation. His anonymity and privacy go up in the flash of a hundred paparazzi cameras. And he's an overnight sensation with his young male students, for reasons that have nothing to do with his brilliant classroom banter. All of which makes him wonder if it's possible to find true love in the hot spotlight of the media.
