Her most famous silver screen turn was in superhero extravaganza Fantastic Four.
And Jessica Alba looked like she was trying to channel the Invisible Woman as she ran errands in Beverly Hills on Monday.
The starlet wore a look of grim determination on her face as she strolled through the well-heeled area of Los Angeles County.
The 34-year-old was looking in typically fine form in an understated ensemble of grey pullover, T-shirt, leggings and flat shoes.
But the silver screen stunner, who is worth an estimated $350 million, made sure she added an extra splash of Hollywood glamour to her look with a trendy pair of designer tinted sunglasses.
She looked keen to keep a low profile as she marched towards her destination with a ladies room key in her hand.
Mother-of-two Jessica recently claimed she had experienced sexism as she set up her business The Honest Company, which sells ‘ethical’ home products.
The self-styled actress said: ‘You feel like a lone wolf surrounded by men who have done it all before.
Meanwhile her company, which in August was valued at $1.7 billion, is currently being sued by consumer Jonathan Rubin for $5 million, who alleges her company ‘deceptively and misleadingly’ marketed its products as ‘natural’ when a number of items included ‘unnatural’ and ‘synthetic” ingredients.
The case between Rubin and The Honest Company is set to be heard in court in San Francisco on January 19, 2016.
