The 30-year-old star was spotted wearing a personalised bikini bearing her new name, Mrs Humphries, as she honeymooned in Italy with her new husband Kris.
The stunning brunette showed off her incredible bikini body in the white two-piece, which had her new surname emblazoned on the bottoms in diamantes.
"We were planning on waiting til next summer to take [a honeymoon]," Kardashian told Us exclusively at Sunday's MTV Video Music Awards in L.A. "But Kris surprised me last minute!"
Adds a source of their uber-affectionate time: "Kim is the kind of bride who'd be thrilled if she had gotten pregnant on her honeymoon."
"Our honeymoon was so perfect!" she told Us at the VMAs. "We caught up on alone time."
