Travis Barker and Kourtney Kardashian made headlines around the world this month with their lavish Italian wedding.

While the nuptials mark the beginning of married life for the Blink-182 drummer and his reality TV star wife, it also means a very clear end to his previous marriage.

At least that's what his ex - who has just put her engagement ring from him up for sale - seems to think.

Before his whirlwind romance with Kourtney, Travis was married to model, pageant winner, and actress Shanna Moakler. The pair shared a relatively high-profile family life together, even appearing on their own reality show, Meet the Barkers.

However, after first tying the knot in 2004 and welcoming two children together (Landon Asher Barker and Alabama Luella Barker), Shanna and Travis went their separate ways in 2008.

Now, in the wake of Travis's splashy Portofino wedding, Shanna has once and for all finalized her split from the rocker by putting her expensive engagement ring from him up for auction.

The Bridalplasty star recently listed the eye-popping Cartier ring on the online jewelry resale platform Worthy. According to the site, the ring is made from platinum and features a central 4.01-carat solitaire-cut diamond surrounded by a smaller 1.04-carat stones. As of today (Tuesday, May 31) bidding is up to $72,360.75.

Despite how it looks, in an interview with Us Weekly Shanna reassured people that there was no animosity between herself, Travis and Kourtney. Instead, she explained that she wants to sell the ring so that they can all move forwards.

The star told the outlet that the Cartier piece had been her "dream ring" at the time - but that "that chapter of my life is over."

As for a price tag, she's hoping it will fetch a whopping $120,000.

Kourtney and Travis' blow-out Portofino wedding ceremony this month marked the third time the loved-up celebrity couple celebrated their union.

After announcing their engagement in October, they first had a non-binding ceremony in Las Vegas earlier this year. Next up was their legal binding ceremony in California, before - last of all - they jetted to Positano to celebrate their marriage in style on May 22.
