Robert and Terri Irwin were all smiles at LAX on Tuesday.

The famous zookeepers looked like they did not have a care in the world as they made their way through the airport and happily chatted with fans.  

Robert, 20, dressed for comfort in a plain green t-shirt paired and tan pants paired with black sneakers.

He accessorised with a smartwatch and had his hands full with black luggage as he checked in at the terminal.

The wildlife warrior demonstrated his commitment to Covid safety by sporting a black facemask and looked to be in good spirits as he laughed it up with his famous mother.

Elsewhere, Terri, 59, showcased her love for Down Under by wearing a dark blue shirt emblazoned with the word Australia.

She completed her look with matching jeans and black sneakers and accessorised with a colourful backpack and a designer handbag slung around her arm.

Terri allowed her blonde hair to hang freely around her shoulders and she sported a matching black facemask to her son.

The mother-son team looked to be in good spirits as they made their way through the busy airport.

The sighting comes after Robert and Terri copped backlash earlier this week after the mother-son duo shared pictures of their recent adventures to Instagram.

'Is Robert and his mother joined at the hip. She is in every pic you see of him,' one person wrote in the comments while another said, 'He's 20 now!'

However there was plenty of support for their close relationship, with one person replying, 'He's a lucky young man to have her.'

Another wrote: 'People saying why Robert has he's mum in so many photos. Remember every day is precious. Life is fragile. The Irwin's like millions of other families have experienced loss on a monumental scale.'
