Halle Berry and Olivier Martinez are reportedly planning to tie the knot this weekend.

The Oscar-winning actress is expected to walk down the aisle at a mystery destination in Europe, according to People magazine.

The 46-year-old beauty and the French actor were spotted jetting off to Paris on Tuesday (09.07.13), accompanied by Halle's five-year-old daughter Nahla, from her past relationship with model Gabriel Aubry.

It has been speculated the couple - who are expecting their first child together - may have the ceremony in France, but a Mediterranean wedding could also be likely.

Halle, 46, and Olivier, 47, began dating in 2010 after meeting on the set of 'Dark Tide' and announced their engagement in March 2012.

It will be Halle's third wedding, whereas Olivier - who previously dated Kylie Minogue - has never been married before.

The 'Cloud Atlas' actress was previously hitched to baseball player David Justice from 1993 to 1996, and to singer Eric Benét from 2001 until 2003.

A source recently said: "Having a baby brings them closer and gives them that much more to share. They are very much in love."
