Halle Berry: I Didn't Think I'd Get Engaged Again

"Who knew [I'd get engaged again]?" she said with a laugh to Extra on Saturday, during her first red carpet appearance since Martinez popped the question.
"I swore it off, right? Never say never, people!"
(She did in fact swear it off, telling InStyle in 2007 that, "I will never, never get married again.")
The ring, which Martinez commissioned from his Paris neighbor, Robert Mazlo, last year, is “a one-of-a-kind piece and cannot be replaced,” the jeweler told PEOPLE exclusively in March.
Martinez, 46, and Berry, 45, met while shooting 2010's Dark Tide and soon became an item off-screen.
The actress was previously married to baseball player David Justice and singer Eric Benét.
