Halle Berry is ready to say "I do" again. 

The 46-year-old actress will be marrying her longtime boyfriend, actor Olivier Martinez in a private ceremony in south France according to People. 

According to People, the couple boarded a plane Tuesday afternoon with Berry's daughter 5-year-old Nahla. Berry and Martinez met while filming 2010 film "Dark Tides," and according to sources the two have been inseparable ever since. 

"They seem truly in love," said Sophie Dulac, president of the Champs-Elyees Film Festival. "I've known Olivier very well and have never seen him like this."

Dulac said Berry called her soon to be husband "the one."

The couple is also expecting their first child together in early fall. This will be Martinez's first child. In April, Berry revealed her pregnancy, which she called "the biggest surprise of my life."

In 2007, Berry told Instyle Magazine that she was no longer considering marriage as an option for her life. 

"I will never, never get married again," Berry told the magazine. 

The soon-to-be married couple were banned from moving Berry's daughter with ex-boyfriend Gabriel  Aubrey, to Paris. 

This will be the first marriage for the 47-year-old Martinez, who previously dated Kyle Mingue. This will be Berry's third marriage. The first was to baseball player David Justice and her second marriage was to singer Eric Benet. 

The couple revealed their engagement in March 2012. Martinez popped the question to the actress with an emerald engagement ring by Paris designer Robert Lazio in early 2012.
