Hank Williams - Williams, Jr. Reconciles With Estranged Wife

The 62-year-old singer, son of music icon Hank Williams, wed his fourth wife, former model Mary Jane Thomas, in 1990 but their rocky romance appeared to be heading for divorce when they parted ways in 2007.

However, Williams, Jr. has since made amends with Thomas and they recently marked a milestone in their union.

A source tells America's National Enquirer, "They almost divorced, but they've happily celebrated their 21st wedding anniversary. I know Hank is proud that they kept their marriage together."

And family was the driving force behind the singer's decision to reconcile with Thomas.

The insider adds, "Hank is a great guy... I don't think he wanted to be a four-time loser in marriage, and he didn't want his children with Mary Jane - Katherine and Samuel - to grow up in a broken home, as his older kids did.

"But most of all, he realised he still loved Mary Jane. They still had that spark."
