Kate Beckinsale In Bikini Celebrates Her MUA

Kicking off the five-part share with a glorious beach-themed snap that portrayed the pair on some sort of a wooden ramp, Beckinsale delivered swimsuit chic in a black two-piece bikini paired with a matching wide-brim hat and dark sunglasses.

Perched atop strappy brown heels, she showed off her endless pins in a standing pose with both arms nonchalantly tucked behind her head. Meanwhile, Aston was laying down at the feet, sprawled on a blue cushion. He wore a black-and-white Hawaiian shirt and dark shorts.

The slideshow continued with an image of Beckinsale in the makeup chair. She was in the midst of getting hair rolls, while Aston applied a shimmering gold palette on her eyes.

Fans were also treated to a hilarious snap from the Jolt movie set, wherein the limber actress showed off her flexibility with a leg hike on a dumpster. As always, her treasured MUA was by her side, retouching her glam.

Beckinsale's Instagram-famous Persian cat, Clive, also made an appearance toward the end and was seen lounging on a makeup table next to a smiling Aston.

Lavishing him with compliments in the caption, Beckinsale wrote: "Happy birthday, Dollylocks, my most favourite [sic] excellent SB, PB and M. Whether it’s going all the way to Africa or sitting in my mum’s kitchen you are eternally the funniest, best, most loyal, bloody good egg ever."

"Dollies for life," she continued, adding a string of cake emoji.

Beckinsale and Aston go way back and have been working together not only for events and red-carpet appearances but on screen, as well. According to his IMDb page, he was the makeup artist for Underworld: Blood Wars and has since worked with Beckinsale on The Widow, Jolt, Guilty Party, and Prisoner's Daughter.

Remember Beckinsale's hilarious IG video in which she appears as her Jolt character, Lindy, and describes her ideal "first date outfit?" Yep, you've guessed it, her bloodied makeup look in the clip was all Aston's artistry!

In case you're wondering, he also did her glam in the above photo of the dramatic swimsuit/sarong-inspired Julian Macdonald gown that she wore at the 2018 GQ Men of the Year Awards.

The duo's most recent collab was for Beckinsale's feature in Flaunt magazine, wherein she showcased a number of designer looks that included a Versace pink latex dress.

Aston also did her glam for the Vanity Fair Oscars party in March, where the ageless beauty turned heads in a sweeping black Zuhair Murad gown with sheer sleeves and a see-through skirt embellished with sequin flowers.

"I love you my Dolly Dolly Dollylocks 💕," Beckinsale wrote in another affectionate IG post shared one month before Aston's December 19 birthday. "Thank you for the best week of roomatery and work and laughs and two soups," she added, posting yet another collection of sweet snaps from work that you can see below.
