In a recent episode of The Rachel Hollis Podcast, the author said her ex-husband's death was "traumatic and awful."

"We still honestly don't know what happened," she said. "I found out after the fact that he had gone to the hospital a couple of times because he was having heart problems.

"So I think it's really highly possible he had a heart attack, but I don't know," she continued. "Whatever he died from, we're still in the same space, which is just deep grief."

Rachel went on to say the couple's four kids were all "riding waves" of grief, but "doing as well as they can."

"We're sad, we're angry, we're confused and we're all the feelings," she continued. "But we are very strong. We are very close. We are a very tight group. And it's gonna take some time, but we are going to be okay."
