The 46-year-old French actor - who met Halle on the set of `Dark Tide` in 2010 - has finally gone public with their plans to marry.

Asked about the engagement, he said: " Yes, of course it`s true."

Speaking ahead of the opening of his new restaurant, Villa Azur, in Miami on 10.03.12, he also set the record straight about who designed the `New Year`s Eve` actress` emerald and yellow gold ring.

Jewellery designer Gurhan claimed to be the brains behind the ring in a statement to People Magazine, but Olivier says it was actually created by Parisian jeweller Robert Mazlo - who he says has been making jewellery for, "kings and queens for many centuries."

Talking to the Miami Herald newspaper, he explained: "There is a jeweller taking credit for doing the ring and it`s a lie! They have nothing to do with this."

It will be the first marriage for Olivier - who has previously dated Kylie Minogue and Rosie Huntington-Whiteley. Halle, 45 - who has daughter Nahla, three, with ex-boyfriend Gabriel Aubry - was married to former baseball player David Justice from 1993 to 1997 and to singer Eric Benet from 2001 to 2005.
