She rarely puts a foot wrong when it comes to her fashion choices.

But pregnant Jessica Alba made a rare misstep - as she ventured out wearing a pair of garish peep-toe wedge heels, teamed with socks.

The 29-year-old actress, who is pregnant with her second child, was spotted arriving at the Radiun Studio in Santa Monica yesterday.

The shoes are in fact the very fashionable Prada Flatforms - a sandal version of the brogue style that made headlines earlier this month.

And indeed besides the questionable combination socks with sandals, the glowing star was looking her usual fantastic self.

She teamed a pair of flared jeans with a black jacket, accessorised with a very stylish Prada bag.

The Fantastic Four star has taken some time out from her busy schedule in recent months to spend some time with her daughter Honor, aged two, before she starts school.
