Kelly Osbourne stuns in sky-high heels and eye-catching hair

Kelly Osbourne Shines in Showstopping Look at Serpentine Gallery Summer Party

Kelly Osbourne made a splash at the Serpentine Gallery Summer Party in London this week, reminding everyone exactly how to command attention on a red carpet. Stepping out in a stunning black Rebecca Vallance gown, Kelly’s glamorous look and bold style choices turned heads—and sparked fresh conversations about her constantly evolving style and image.

A Defining Red Carpet Look

Osbourne, 40, dazzled onlookers in a strapless black gown featuring a structured bodice and dramatic square neckline lined with gold accents. The satin dress, cut elegantly above the ankle with a mini train, was paired with towering open-toe platform heels, emphasizing her statuesque poise. A delicate diamond necklace completed her minimal yet high-impact ensemble.

Her style statement extended to her hair and makeup, with her platinum blonde locks styled in soft waves cascading across her shoulders. The overall effect was further heightened by a smokey eye, subtle blush, and soft pink lips—her makeup artist balancing Hollywood glamor with modern edge. As she shared on Instagram, "The bigger the hair, the closer to GOD!" a nod to her playful embrace of voluminous styles and dramatic transformations.

The Evolution of Kelly’s Signature Style

Kelly’s appearance at the star-studded event wasn’t an isolated moment. Earlier this year, she swerved away from her iconic purple hair, debuting striking platinum blonde and silver hues instead. This radical change had her fans doing a double-take and ignited discussions online about her wider aesthetic evolution. Her stylist has revealed that Osbourne’s new extensions and expert styling tools were behind the voluminous, cascading ‘do at the party.

While Kelly has always been adventurous with her hair—ranging from lavender bobs to edgy pixie cuts—she’s previously shared that unconventional color and styles make her feel "like me." Osbourne told PEOPLE, "I’ll never be normal or simple. The most insulting thing someone said to me was to call me ‘beige’"—making each transformation more than just a fashion statement, but also a personal declaration of individuality.

Fan Reactions and Social Media Buzz

Kelly’s Instagram posts regularly spark a frenzy among followers. Notably, her recent glam reveals—including a carousel of images in a velvet black robe and flawless makeup—set social media alight with fans debating the extent of her transformation. Conversations have swirled around her sharply defined features and strikingly smooth complexion, with some attributing the changes to changes in skincare, makeup artistry, weight loss, and rumors of cosmetic procedures.

After her latest reveal, some fans speculated about the role of weight-loss medications and surgery, with Kelly pushing back. She attributed her look to disciplined habits following gestational diabetes during pregnancy, explaining, “I continued the diet and a lot more steps,” and embracing motherhood’s inherent workout routines.

A Star Among Stars

The Serpentine Summer Party is annually celebrated for its high fashion and celebrity guest list, and this year was no exception. Attendees included Lady Kitty Spencer in sheer turquoise, Isha Ambani in an embellished gray mini dress, designer Rebecca Vallance in metallics, and Minnie Driver in rich velvet blue. Yet, it was Osbourne’s classic-with-a-twist ensemble and unforgettable hair that stood out as a highlight of the evening.
