Proof That No-One Does Pregnancy Style Quite Like Blake Lively

Blake Lively is nailing it.

Blake Lively's already faultless pregnancy style just got even better. The actress, creator of lifestyle website Preserve and all-round wonder woman rocked up at L'Oreal's Annual Women Of Worth Celebration looking incred.

Historically, dressing a baby bump on the red carpet has proved tricky for some, with many opting to conceal their blossoming tums under metres of fabric, with varying degrees of success.

Not Blake, though. The 27-year-old is clearly revelling in her first pregnancy and graced the red carpet in New York wearing a clinging, backless, oh-so-sexy black gown with bump on full display.

Worth a mention, as well, was her hair. Tousled and gorgeous, of course, but we couldn't help but notice her roots. Whoever knew this golden girl was so naturally dark? Whether this is a new trend the star is trying on for size, or she's stopped dying her hair due to her pregnancy we don't know, but she looked great either way. How could she not?

The L'Oreal's Annual Women Of Worth Celebration acknowledges 10 women who are all making a difference in the world with the winner taking home $25,000. On the night, Blake accompanied Brittany Wenger, who, at 15, created a tool to diagnose breast cancer, helping women detect cancer early.

Blake wrote on her Instagram account, alongside a snap: 'Celebrating tonight with the incredible Brittany Wenger. Google her! At 15 years old she started a program that has helped detect cancer with 99% accuracy. She's 19 years old now and has only just begun to change our world. I'm humbled to have been her date. Who inspires you? #bethechangeyouwanttosee #lorealwomenofworth.'

Truly inspiring.
