Third time's the charm for Halle Berry.Sources say that French actor Oliver Martinez popped the question over the holidays, proposing to the Oscar-winning actress with a diamond-and-emerald ring. 　　The couple has been dating for over a year and met in 2010 while filming the movie "Dark Tide", which will be released this year. 　　It will be the third marriage for Berry, who has a 3-year-old daughter, Nahla, with her ex-boyfriend Gabriel Aubry. The 45-year-old star wed former baseball player David Justice for four years in 1993. She later tied the knot with R&B singer Eric Benet in 2001, but that relationship also came to an end in 2003. 　　On the other hand, her French beau, who is 46, was previously linked to Australian pop star Kylie Minogue for several years, before parting their ways in 2007.
