Mother-of-three Zoe Saldana has a stunning figure.

And on Monday the 42-year-old star of the blockbuster films Avatar and Guardians Of The Galaxy reminded her 7.3M Instagram followers of that.

Saldana had a flat tummy and sculpted legs as she rested back on her arms while positioning one leg akimbo.

The siren had her long hair worn down as she let fans look at her ombre color.

And Zoe also had on ruby red lipstick which went well with her pink outfit as she shared a coy smile. The Star Trek actress kept her look simple as she did not have on any jewelry. 

She was posing for a good cause.

'I wear pink in honor of all women I know and love who have battled breast cancer,' said Zoe.

'It’s breast cancer awareness month and I’m joining my friends @kitundergarments company for #kitstokickcancer!

'They have partnered with @wcrfcure and will be donating 5% of sales for the entire month of October. In addition, they will donate $1 to @wcrfcure for everyone who posts a photo in their undergarments. Be sure to tag them and use #kitstokickcancer.'

So far Kate Hudson, Katy Perry, Mindy Kaling and Dakota Fanning have also been a part of the movement.

Zoe has three kids with husband Marco Perego - twins Bowie and Cy, five, and Zen, three. 

Earlier this month, Zoe shared an empowering message with her 7.3 million Instagram followers by sharing a close-up selfie - in which she appeared to shed a tear.

The actress captioned the shot, 'Don't let your mind bully your body,' with the hashtag, #loveyourself.'

In the black-and-white clip on Instagram Stories, the A-list actress had her dark locks pulled  back in a neat ponytail as she wore an Adidas activewear top.

Saldana has often used her platform for causes including social change and gender issues, having blazed a Hollywood trail with her appearances in blockbusters like Avatar and the Star Trek and Guardians of the Galaxy films.

The New Jersey-born beauty and husband Perego, 41, exchanged vows in 2013.

She said last year during a speaking engagement at in Amsterdam that she sought to play 'a whole woman' in her roles, according to Thomson Reuters Foundation

'I'm not actively playing a strong woman,' she said, 'I'm just playing a whole woman versus something that is just there to be objectified and fill in all the boring spaces in a movie that come from a weak storyline.'

She added, 'When I go for a job, or I start a business or I make a decision, it has never been because I'm a woman or because I'm a person of color. It is because I'm a human, I'm a voter, I'm a taxpayer, I'm a human being and because I matter.'

She said that studios were moving in the right direction in adding breadth and depth to female roles both on screen and in the writers' room.

'Women are so relevant in life, and in all places, that the logical thing to do is to capture them accurately and build them accurately,' she said.
