Gavin Rossdale did not mince words about his feelings toward his very public divorce from ex-wife Gwen Stefani.

In an interview with The Guardian , the Bush frontman was asked to name his most embarrassing moment, and he candidly responded: The gross and lopsided specter of the crumbling of my marriage.

Rossdale had been married to Stefani for nearly 13 years when they announced in August 2015 that they came to the mutual decision that we will no longer be partners in marriage. They added that we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment.
