Even Michelle Rodriguez doesn't understand why the paps are interested in her ... but she loves the attention!

The former "Lost" star was giddy as photogs caught her sneaking out the backdoor of trendy clothing enclave Kitson in Los Angeles.

Smiling and joking with paps, Rodriguez tried to playfully shake the snappers, exclaiming, "Hey look, Brad Pitt!" While the photogs didn't fall for it, they were definitely on high alert the rest of the day.
