Kim Kardashian accidentally caught wearing seductive silver swimsuit to celebrate her 44th birthday in Malibu with family

Kim Kardashian showed off her age-defying physique as she kicked off her 44th birthday celebrations over the weekend. The SKIMS founder hit the beach with her closest family and friends on Saturday afternoon in sunny Malibu — one day before her actual birthday on October 21.

Kim — who recently had a slumber part with Pete Davidson’s ex — looked incredible as she waltzed around in a skimpy silver bikini that showed off her famous curves.  Kim’s sisters Khloe Kardashian, 40, Kourtney Kardashian, 45, Kendall Jenner, 28, and mom Kris Jenner, 68, took time out of their busy schedules to attend the beach bash held at a luxury oceanside property. The youngest of Kim’s four kids with ex-husband Kanye West — Chicago, six, and Pslam, four — were also present.

The Kardashian-Jenner clan appeared to be filming scenes for their hit Hulu reality TV series, The Kardashians, as they were joined by a camera crew. Missing from the action was Kim’s younger half-sister Kylie Jenner, 27, and her reclusive younger Rob Kardashian, 37.

Kim’s sexy silver swimwear look also featured a sheer, floor-length sarong that hung off her hips as she climbed a set of outdoor stairs. Her long raven hair fell to her waist in wavy strands and she wore full glam makeup.

At one point, Kim decided to cover up by placing a white beach towel around her waist during a break between filming. She looked in a happy mood as she was caught flashing smiles at her family and crew members throughout the beach hangout.
