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 be in a happy mood as she was caught flashing smiles at her family and crew members throughout the beach hangout.

Chicago and Psalm were seen running around the beach with one of their nannies in close proximity.

Kim’s daughter North, 11, and son Saint, eight, were not present for the family gathering in Malibu.

However, Psalm and Chicago did have the company of their cousin True Thompson, who is Khloe’s eldest child with ex-boyfriend Tristan Thompson.

The young cousins had a blast while their moms taped an intimate sit-down convo with Kendall and Kris at an outdoor table.

The Good American founder kept a watchful eye on True, often checking on the six-year-old when cameras weren’t rolling.

She and Tristan — who split in 2021 following his paternity scandal and most recent cheating incident — also share two-year-old son Tatum, who was born via surrogate.

Later, Khloe stripped off her robe to unveil a busty black one-piece suit. She layered up with the look with sheer, colorful sarong.

Kendall looked runway-ready in a slinky black dress that hung off her slender figure.

The runway maven wore it over a classic black string bikini that included cheeky thong bottoms.

Kendall continued to rock her new blonde hair, which was worn in an effortless half up, half down style.

The eldest Kardashian sister, Kourtney, kept a low-profile in a black sweatshirt and sunglasses as she spoke to her sisters under a shady tree.

Kim rang in her 44th birthday on Sunday and received out outpouring of love from fans, her family and her celebrity friends, like Ivanka Trump.

For her special day, the mother-of-four slipped in a nude ‘birthday suit’ dress that consisted of a beige bodysuit worn over a sheer glossy dress.

She went braless in the outfit, which fit her like a glove.

She shared a full-length look and close-up shot of the sexy outfit to her Instagram Stories early Monday morning after partying the night away with friends.
