Pregnant Kim Kardashian -- I'm Glad Kanye Went After that Photog

Kim Kardashian is turning into a real bad ass ... she's telling friends she thinks Kanye West was spot on when he lunged and swore at a paparazzo in Bev Hills.

Kim -- who is always impervious to the gaggle of photogs who chronicle her every move -- thinks Kanye was justified when he bolted out of a restaurant and went all Incredible Hulk on an unsuspecting camera guy.

As you know ... Kanye had a close encounter with a metal sign as he walked to 9021PHO, slamming his forehead UFC style with a souvenir that will probably last for a week.

Kim is telling friends ... the paparazzi have become increasingly aggressive with both of them since she became pregnant. She's especially upset because on Monday a photog chased her down while she was driving and she had to swerve into another lane to avoid him and almost got into a bad accident.

Bottom line ... Kim is encouraging Kanye to take care of business when a photog crosses the line. The problem with her theory -- in the case of the sign, the photogs held their distance and Kanye just didn't look where he was going.

The truth hurts.
