Lara let her natural beauty shine through as she stepped out without a lick of makeup.

While Sam took care of most of the luggage, he kept an eye on his sons Rocket, six, Racer, four, and River, one.

It comes after Sam gave rare insight into his family life with Lara and their three children during an interview on The Kyle and Jackie O Show on Friday.

The Transfusion star gave some fatherly advice to new dad Kyle Sandilands after he welcomed his first son, Otto, five months ago.

He said there is no right or wrong way to be a father after Kyle admitted he “should have read a book or something” before the birth of his son Otto.

‘Books don’t tell you anything… It’s a practical experience and you learn as you go. That’s what Lara and I are doing,” Sam said.

Sam’s mention of his wife caused Kyle to ask how his old friend Lara was doing and make an interesting observation about the famous couple.

Neither of them has aged. Do you use any secret Hollywood serum? she asked her.

‘I think I’m getting old!’ Sam answered. ‘Lara is like Benjamin Button, she’s aging backwards. She is getting prettier.
