The former Bridalplasty host has been involved in several high-profile relationships over the years. Shanna previously dated British singer Billy Idol in the '90s, and the two briefly appeared in the 1998 film The Wedding Singer together.
Following her split from the "Cradle of Love" singer, Shanna began seeing Olympic boxer Oscar De La Hoya in 1997. The couple announced their engagement in October of 1998, and Oscar is the father of Shanna's eldest child, Atiana.
The pair parted ways in 2000, and Shanna later filed a palimony suit against her ex. The matter was settled out of court the following year, but the settlement amount has not been publicly shared.
Shanna went on to date The Parent Trap actor Dennis Quaid, but they broke up after less than a year together.
The actress married Blink-182 drummer Travis Barker in 2004. The spouses notably went on to star on the MTV reality series, Meet the Barkers, together, along with their two kids, Alabama and Landon (Atiana also appeared on the show). The show lasted for two seasons, and it ended in 2006 — which is the year that Travis first filed for divorce from Shanna.
After a 2007 reconciliation, Travis and Shanna's divorce was finalized in early 2008.
Once her relationship with the rocker formally ended, Shanna had public relationships with biker Bryan Sollima and model Matthew Rondeau (the two are currently back on in their on-and-off romance). As many already know, Travis has since gotten engaged to Kourtney Kardashian.
While Travis will likely be appearing on the Kardashian family's upcoming Hulu series, Shanna can next be seen on Season 3 of Big Brother: Celebrity Edition.
The limited series airs on weeknights (until Feb. 23) at 8 p.m. ET on CBS. You can also stream the series live or on demand on Paramount Plus.
