Charlize Theron sizzles in white during beachside Miami photo shoot... before taking a break to dote on son Jackson

She first found fame as a model in her native South Africa.

So it's no surprise that Charlize Theron posed and pouted like a pro during a photo shoot on Wednesday.

The 38-year-old showed off her incredible figure in a sleeveless white dress as she smouldered for the camera during the shoot in Miami, before doting on son Jackson between shots.

The statuesque beauty first wore a fitted white dress that sported tassels at the hem.

She was seen striding along a wooden walkaway alongside a man clad in Speedo-style
swimming trunks and a blue shirt.

Charlie wore her blonde hair wet and slicked back and kept her make-up natural, highlighting her eyes with smokey shadow and her cheekbones with a dusting of bronzer.

The Oscar winner was then seen in another white frock, an elegant number which sported lace-up ties on either side.

Her hair had dried somewhat and looked naturally curly, befitting the oceanside scene.

Charlize slipped effortlessly into 'mom' mode as she doted on son Jackson, who paid her a visit on set.

Meanwhile, Charlize and her new boyfriend Sean Penn, 53, are allegedly already talking about moving in together and getting married.

The pair have been inseparable since spending the holidays in Hawaii.

And new aerial shots of Sean's house hint that he's already baby-proofed his place with a fence around the swimming pool, and added a trampoline, suggesting Charlize and Jackson may already be calling his place home.

Charlize has previously stated that she is not keen on the concept of marriage, saying back in 2011 that tying the knot was 'never something that was important [to me].'

Sean divorced second wife Robin Wright in 2010 after 14 years of marriage, with the pair sharing a daughter Dylan, 23, and a son Hopper, 20.

He was previously married to Madonna for four years in the 1980s, while Charlize was in a long-term relationship with Irish actor Stuart Townsend, 41.
