Gwen Stefani married Blake Shelton this weekend, but one person who many fans are asking about is her ex-husband.

Gavin Rossdale and the "Hollaback Girl" hitmaker tied the knot in 2002 and divorced in 2016. They share their kids, Kingston, 15, Zuma, 12, and Apollo, 7.

But outside their children, it was reported that Gwen and Gavin don't have a relationship and don't even communicate with one another.

An insider revealed to Hollywood Life that the former couple doesn't have a close relationship even after their marriage.

When they do talk about the kids, they keep it as very minimal as possible.

The insider added, "They have lived very separate lives for a while now and don't get along."
