Kim Kardashian stepped out in a sweater and denim shorts while heading to lunch in LA on Thursday. She was wearing arguably more clothing than the last time we saw her. Kim shared a sexy snap of her postbaby body in an Instagram photo that basically broke the Internet earlier this week. She sported a low-cut white swimsuit that showed off her ample backside and added the caption, "#NoFilter." Kim may be gearing up for a fun weekend with friends and family as she rings in her 33rd birthday on Monday. She announced her annual celebration plans — hosting a giant party at Tao Las Vegas on Oct. 25 — via social media earlier this week. Coincidentally, her boyfriend Kanye West will also be in Sin City that night. Kanye is set to hit the stage at the MGM Grand Garden Arena as part of his Yeezus tour.
