According to reports, Halle and Olivier - who are expecting a baby boy together - have flown to a mystery location to tie the knot.
The couple were seen jetting out of Los Angeles and sources have apparently told E! that they want to make things official by the time their baby comes along.
If Halle does wed Olivier this weekend, it will be third time lucky for her. In 1993, she married baseball player David Justice, but they separated several years later before divorcing in 1997.
The Hollywood star then married singer/songwriter Eric Benét in 2001, however it wasn't to be and they divorced four years later.
She has since gone on to have a daughter, Nahla, with French Canadian model Gabriel Aubry, however their split in 2010 was far from amicable.
Despite having several high profile relationships, Olivier has never been married and proposed to Halle in March 2012. They then announced they were expecting a baby together last October.
