Do you know who Coco Rocha is? Why now you will

Pregnant supermodel Coco Rocha has vowed not to let her pregnancy slow her down and will maintain her jet-setting lifestyle.

The 26-year-old supermodel - who announced she is expecting her first child with her husband James Conran earlier this month - says their unborn baby is "already racking up some air miles," as she is still as busy as ever.

Asked how she is feeling, the brunette beauty told PEOPLE magazine: "I'm a little sleepier than usual - but finding time for naps helps a lot. I'm still travelling for work, so this baby is already racking up some air miles!"

The star has just released her book, 'Study of Pose,' and admits she isn't a fan of selfies.

She said: "It's sort of kitschy - there is definitely a 'Blue Steel' and 'Le Tigre' in there. But on the other hand it's a legitimate reference book."

She added: "If the book proves anything, it's that there should not just be one 'go-to' pose. Mix it up. And do not take selfies. Hand the camera to someone else."

The model announced her pregnancy on her Instagram site by posting a video of herself in a nude leotard showing a hint of a baby bump and featuring the words, 'Baby Conran arriving spring 2015".

She also wrote: "We are absolutely thrilled and elated to announce that after four years of marriage we are expanding our family and expecting our first child spring of 2015!"

The couple - who tied to the knot in 2010 - are yet to reveal whether they are expecting a boy or a girl.
