Hello, sunshine! Olivia Palermo has once again transformed from brunette to blonde.

The Manhattan-based socialite first debuted her lighter hair color earlier this week at Paris Couture Fashion Week. Palermo's most recent appearance came Wednesday, July 9, at the Valentino show, which she attended with her new husband Johannes Huebl.

For the occasion, Palermo, 28, left her glossy beeline honey tresses parted down the center in a sleek and straight style. Though it was raining in Paris, the former MTV reality star had no concern about keeping her hair intact as Huebl dashingly held up an umbrella.

The stylish star wore a collared long-sleeve white shirt, neatly tucked into a flouncy navy skirt trimmed with red.

The gorgeous newlyweds, who got married on June 28 in Bedford, NY, have been happily posting updates from Europe in the last week. On Monday, July 7, Palermo shared an Instagram picture with her German model hubby at the Guerlain House on the Champs Elysees.

"Kicking off a fashionable week," she wrote.
