But Lancaster said she was careful with her approach and was mindful of the kids.

"I tiptoed very lightly," she said.

"Because there were lots of personalities, and more important, there were children ranging from all ages."

The musician also added about their relationship: "There is a maturity I may have taught Penny and there is an honesty she has taught me."

The pair met back in 1999 and married in 2007.

Stewart has always been a family man and in total, he has eight children from his three marriages and ex-girlfriends.

"I have to be several different fathers because of the different age groups of my kids," Rod previously said, according to People.

"You really have to treat all of them as individuals with individual problems.

"What makes me happiest now is seeing all my kids and my wife with big smiles on their faces."
