Kourtney Kardashian and Travis Barker's daughters were bridesmaids and flower girls at their Italian wedding

The pair were seen walking down the aisle in mushroom-coloured netted gowns with red poppies embroidered on them, with red roses in their hands and a single red flower in their hair.

Travis' step-daughter, Atiana De La Hoya, 23, was seen walking ahead of Penelope and Alabama in a similar gown.

The celebrations continued with a reception at the historic Castello Brown castle in the hills of Portofino.

Kylie Jenner took to her Instagram Stories to share a series of videos from inside the party, where fresh cannolis and pasta were being served.

After wowing in a white Dolce and Gabbana mini dress with a long embroidered veil when they said their 'I Dos', the 43-year-old reality star changed into a lacy black number, complete with a shorter black veil, as Travis seductively bit off his new wife's garter on the dancefloor.

The pair's first dance was to 'At Last' by Etta James.

Kourtney - who also has Mason, 12, and Reign, seven, with Scott - and Travis' wedding guests included the bride's mom Kris Jenner and her partner Corey Gamble, sisters Kim Kardashian, Khloe Kardashian, Kendall Jenner, and her boyfriend Devin Booker.

Travis' best friend Machine Gun Kelly and his fiancée, Megan Fox, and his Blink-182 bandmate Mark Hoppus and his wife Skye were also in attendance.

The couple had recently exchanged vows in a "practice" ceremony in March, before making their union official in a Santa Barbara courthouse last weekend, and then tying the knot in front of family and friends in Portofino.

According to MailOnline, Kourtney entered the garden for the outdoor ceremony at Castello Brown on the arm of her mother while a woman sang 'Ave Maria'.

They then exchanged vows as dusk fell, before posing for photos ahead of further celebrations this evening.
