Kim Kardashian certainly turned heads today when she stepped out in Portofino, Italy, hours before her sister Kourtney's wedding.

The whole Kardashian-Jenner clan have travelled to the Italian coastal town ahead of Kourtney's lavish wedding to Travis Barker.

And just hours before the pair say 'I do' at their stunning castle ceremony, Kim emerged from their five star hotel with two kids in tow.

The reality star took her daughter North and Kourtney's daughter Penelope out to grab an ice cream, presumably while bride Kourtney is preparing for her big day.

Kim looked sensational in a skintight grey catsuit with a crucifix chain swinging from her neck as she walked down the cobbled streets in her killer heels, writes The Mirror.

Kim is still sporting her ice blonde locks after copying Marilyn Monroe's signature look when she wore the late actress' former dress at the Met Gala earlier this month.

Joining the reality star family at the Italian service will be Travis' kids and extended family.

While Megan Fox has also been spotted in the village and Beyonce seen checking into a hotel nearby.

It's not known whether Queen Bey will be gracing the lovebirds with her presence, but she did invite Kravis to her Oscars party with Jay-Z earlier this year.

While they are celebrating with friends and family this weekend, Travis and Kourtney actually got married earlier this month.

Kourtney confirmed her legal wedding to Travis with an Instagram post.

The reality star shared a photo with her 177 million followers on Monday showing her and her new husband seated in a black convertible kissing with “Just married” and cans tied to the rear bumper.

Kardashian’s accompanying caption said: “Till death do us part.”

The drummer shared an identical post to his 6.9 million followers with the same image and caption.

The couple had earlier held a “practice” wedding after the Grammys in April hosted by an Elvis impersonator at 2am.

The joint confirmation on Monday from Kardashian, 43, and Barker, 46, comes a day after US media reported the pair had legally wed at a courthouse in Anacapa in Santa Barbara, California.

The small ceremony was attended by Kardashian’s grandmother and Barker’s father.

The pair got engaged in October last year after being friends and neighbours for years.
