Over the weekend, Kate Beckinsale turned heads at Leonardo DiCaprio's birthday bash in Los Angeles, sporting a dazzling mini dress adorned with what can only be described as a bling-tastic blue-gemstone belt. The internet, as usual, went into a frenzy, sharing the snapshot of Beckinsale's glamorous black frock far and wide.\r\n\r\nREAD: Shantae Advance: Risky Revolution Expands to Include Versions for PS5, PS4, Switch, and PC\r\nKate Beckinsale's Stylish Entrance: A Birthday Bash to Remember\r\nNow, while we all appreciate a good sparkle, one burning question remained unanswered: What's the deal with the gem? Is it a blue diamond or a blue sapphire? It's like choosing between pizza and tacos - both are great, but you still gotta pick one.\r\nDiCaprio's Celebration Unveils Kate Beckinsale's Iconic Fashion Moment\r\nThe blue diamond theory gives a nod to the iconic heart-shaped gem from "Titanic," the movie that saw another Kate stealing DiCaprio's heart. However, there's a slight glitch in this theory - the Heart of the Ocean is, well, heart-shaped. So, maybe it's a cheeky homage to Beckinsale's role as Ava Gardner in "The Aviator," where she rocks a square-cut blue sapphire necklace and declares she's not for sale. You go, girl!\r\nDiCaprio's Celebration Unveils Kate Beckinsale's Iconic Fashion Moment\r\nNow, brace yourselves for the plot twist: this fabulous gem of a dress wasn't a custom creation for the event. Nope, it strutted right off the runway from The Blonds Fall-Winter 2023 collection, showcased during the New York Fashion Week in February.\r\n\r\nThe collection, inspired by Hollywood glam and adorned with motifs that scream "more is more," seems like a page torn from the diary of Elizabeth Taylor. The minds behind this extravaganza are none other than Phillipe Blond and David Blond, the dynamic duo that brought us a parade of sculptural corsets, velvet gowns, and sequined party dresses. Oh, and oversized gemstone motifs? They were practically the cherries on top.\r\nBlue Gemstone Mystery: Decoding Kate Beckinsale's Birthday Elegance\r\nNow, back to our gemstone queen, Kate. She didn't just stop at the dress. No siree! She paired it with black tights, continuing the "who needs pants?" trend. The runway version was even shorter, presented as a top. Add sky-high reflective platform heels and a bold black hair bow to the mix, and you've got yourself a recipe for red carpet domination.\r\nRunway to Reality: Kate Beckinsale Rocks The Blonds' Collection at Leo's Party\r\nSure, the guest list boasted big names like Beyonc\u00e9, Jay-Z, Salma Hayek, Kim Kardashian, Zo\u00eb Kravitz, and Channing Tatum, according to Harper\u2019s Bazaar. But let's be real, no one else brought such a chic sartorial Easter egg to the party. Beckinsale stole the show, turning the night into a dazzling win. Leonardo, who? It's all about Kate and her gemstone glam!
