Pregnant Teresa Palmer shows off her growing bump, expecting a baby girl in April, Adelaide

She's six months pregnant, but Teresa Palmer shows no sign of slowing down anytime soon.

The 32-year-old actress is currently back in Australia for the holidays, spending Christmas in Adelaide with her family.

Seemingly determined to make the most of the summer weather, Teresa was spotted at a local beach on Thursday with her husband-of-five-years, actor Mark Webber, and their two sons, Bodhi, four, and Forest, two.

Wearing a grey and white striped T-shirt dress, Teresa was seen shoveling sand on the beach with her two little boys.

Her long blonde hair was styled into a messy bun and she wore a pale blue scarf tied around her head.

Teresa also carried a small black cross-body bag and accessorised with a pair of pale pink sunglasses.

Her sons appeared to be having a great time running around on the sand, and they had no shortage of beach toys to play with. 

At one stage, the Hacksaw Ridge star was spotted shaking sand off a beach towel as her husband snapped photos on his iPhone.

Mark, 38, wore grey shorts and a plain white T-shirt for the outing, protecting himself from the son with a baseball cap and shades.

Teresa announced her pregnancy in October, telling her Instagram followers she would be expecting a baby girl in April 2019.
