It has been a long wait, but Lara Bingle has finally announced the name of her second baby - who was born five months ago.

Lara Bingle-Worthington and her actor husband Sam Worthington welcomed their second child in October last year - and until now, have kept everything under wraps.

But in an interview with Harper's Bazaar magazine, the Australian model has kept with tradition - and given her second son quite an unusual name.

First we have Rocket, now we have Racer.

Racer is the second child for the celebrity couple, who had their first child, Rocket Zot, in March 2015.

Based in New York, Bingle-Worthington jumped to the defence of Rocket Zot's name - after speculation circulated among Australian media that it was actually fake, reported news.com.au.

"My son's middle name IS a respectful nod to my late father, whose nickname was affectionately, Zot," Bingle wrote on social media one month after he was born.

Taking to Instagram to share the magazine's cover, the entrepreneur and model is the founder and creative director of skincare brand, The Base by LB.

Bingle and Worthington first began dating in September 2013, and they reportedly wed in the Maldives around New Year's Eve 2013.

The family are now based in the US, travelling back to Australia for work.
