British starlet Sienna Miller flew into LAX this weekend -- and received a rude welcome from a gaggle of noisy shutterbugs.
When paps spotted the "Factory Girl," they asked if she were in town to see her controversial, recently-separated beau, Balthazar Getty. Sienna coyly responded, "I work here, I'm an actress."
Things took a sour turn when a photog asked Miss Miller if she were a homewrecker -- and if she felt sorry for Getty's children with his estranged wife, Rosetta. The unamused Miller snapped, "I'm sorry you're so unhappy as a person that you feel the need to say things... that you would never understand."
