Chris Hemsworth got in some mother-son bonding on Saturday when he was spotted arriving at Sydney International Airport with his mother Leonie van Os.

The duo just flew in from Los Angeles and were waiting in line to catch a taxi back home as they took the chance to have a chat.

The Thor star, 40, flashed his silver wedding band as he showed off his bulging biceps in a khaki T-shirt.

Hiding his eyes behind a pair of dark sunglasses, the Hollywood hunk showed off the tattoo on his inner forearm as he leaned against the barrier.

He waited patiently with his mother as aviation services ushered the crowd through the line toward the taxis.

In a post shared to Instagram, the 47-year-old Spanish actress poked fun at her Australian actor love facing the ravages of time.

Alongside a photo of Chris looking shocked, she wrote: ‘That’s exactly the face I made when I turned 40, my love. But don’t worry, it’s gonna be okay!

‘I’ll be here for you too hold your hand and give you all my beauty secrets, even if you look better than ever. Happy birthday!’ she added.

Chris celebrated the special birthday surrounded by friends and family, and even enjoyed a surf with brother Liam.
