Shanna Moakler auctions off Travis Barker's ex ring after he married Courtney Kardashian

Shana Moacker leaves her past behind.

The 47-year-old Big Brother of Celebs graduate sold her engagement ring from her ex-husband Travis Barker following his recent marriage to Courtney Kardashian.

Fourteen years after her divorce from drummer Blink 182, the reality show star has teamed up with jewelry retailer Worthy to sell her round 4-carat solitaire ring with a diamond-studded band. She was married to Barker from 2004 to 2008.

"We don't know exactly what Shana is up to with the money," Stephen Schneider, executive director of WORTHY.COM, told PEOPLE. "But trust me, he will use the results to turn memories into new possibilities, as many of our vendors do." According to Schneider, Worthy will help Moakler "make the most of his engagement ring."

The auction runs from Friday to Tuesday. The current top bid is over $64,000.

"Based on activity to date and the feedback we've received from our exclusive network of professional buyers, we believe we can meet Shanna's reserve price," added Schneider.

Moakler's decision to part with his ring comes just days after Barker, 46, married Kardashian, 43, in a lavish wedding ceremony in Italy on Sunday. Moakler's daughters, Alabama Barker and Atiana de la Hoya are bridesmaids at a ceremony in Portofino, Italy. His son Landon Barker was also involved in the marriage. In April, the musician and Kardashian star previously had a legal ceremony in Santa Barbara and "wedding training" at the One Love Wedding Chapel.

Moakler sent his best wishes to the couple in an exclusive statement to PEOPLE following the surprise ceremony in Las Vegas.

"Congratulations on the happy couple," he said. "I wish them the best that life offers as they travel together."

The former Miss USA took some time to herself after her ex-husband, Kardashian, asked the question. "Temporarily closed for spiritual support," Moakler posted on his Instagram Story in October 2021, apparently in response to the engagement.

In May 2021, Moakler shared a video of Barker's name being removed from his wrist during a laser tattoo removal session.
