Olivier Martinez confirmed his engagement
to Halle Berry
in March, but up until now, Berry has been mum.
"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.")
, 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.
