"We invited only 50 people to make it an intimate wedding," Cara told Vogue Mexico. "It was untraditional, highly personalized, and SO much fun!"

The couple wed in a California ceremony held in Beverly Hills on May 5 at a private residence from Million Dollar Luxe. Actress Santana, 41, wore a long-sleeved silk wedding gown complete with a train and low back designed by Daniel Frankel for the nuptials, while Thirty Seconds to Mars drummer Leto, 55, wore a black double-breasted Amiri suit with wide-leg trousers.

Santana then changed into a backless silk halter top and white pants for the wedding reception, also designed by Daniel Frankel, and accessorized her two looks with a pair of vintage Christian Louboutin heels.

"We invited only 50 people to make it an intimate wedding," Cara told Vogue Mexico in an interview published June 11. "It was untraditional, highly personalized, and SO much fun!"

Among the guests were Santana's famous friends Olivia Culpo, her Salem costar Ashley Madekwe and Stephanie Sugnami. Culpo, 33, who attended the wedding with her husband Christian McCaffrey, wore a black dress that showcased her baby bump.
