Kate Beckinsale In Skimpy Pool Bikini Leaves Fans 'Simply Speechless'

Kate Beckinsale is back in her bikini, and she's looking better than ever at 50. Dropping jaws in her latest Instagram share, the actress showed off her chiseled physique in a skimpy two-piece, posing both in and out of the water as she enjoyed an outdoor pool. Quickly gaining comments for her gallery, Kate hung out with pal Ashley Kechian, although the comments were mostly geared toward Kate and her age-defying looks. While one fan told the Pearl Harbor star that she looks "fantastic," another admitted that they were "simply speechless."

Scroll for all the photos. Kicking things off with a demure snap, Kate posed waist-deep in the water and with her back to the camera. Stripped down to a strapless orange bikini, the Hollywood sensation flaunted her toned back and shoulders, also turning her head to the side as she showed off her features. Flashing a back tattoo as she wore a bouffant up-do and kept her hair away from her face, Kate added in chunky earrings, with the second slide showing friend Ashley smiling.

In a triumphant return, Kate struck poses from an outdoor space while modeling her itty-bitty bikini, plus a knee-high pair of platform boots. Showing off her bandeau pastel swimwear and its chic bust clasp, Kate Beckinsale let her near-matching, open duster billow around her, flaunting her impossibly toned legs and highlighting her killer abs.

Giving a nod to the "'60s" mention in her caption, the actress donned funky, heart-shaped shades and a massive hair bow in this slide, sending out a sassy smile and seemingly having plenty of fun. Further photos, meanwhile, showed Kate and Ashley's manicured nails, some late-night waterfall fun, plus a snap of Kate in a different pair of heart-shaped sunglasses. "Girls trip/60’s vibes/breathing," a caption read.

Kate, who is followed by 5.6 million on Instagram, was asked: "How are you still this mouth watering," with another fan reminding the star that they were left "speechless."

Fans got the star's sensational figure in April as this selfie turned heads. Kicking one leg up as she posed from a chair while modeling a skimpy black lingerie set, Kate wore the same black hair bow, adding in statement platform heels and parting her lips for a little provocation.

"Now that I have your attention . Could you please all go wish @stu_clarke_ a happy 40th birthday. You have no idea what people are going through . Kindness helps .
