Those boots may be made for kicking Heidi Montag's phony ass walking, and the girl wearing them may be an absolute knockout, but even Lauren Conrad isn't above being singled out by the pain-in-the-a$$ security guards at LAX.

Like everyone else, airport security made Lauren Conrad take her (hot!) boots off before boarding her flight in Los Angeles, Calif., on Monday afternoon.

No word if Spencer Pratt and his lame gold chains were similarly detained, but Heidi Montag and her fake engagement ring likely got through.
