The very on-off couple were previously engaged before scrapping the commitment last year.

Now the Jonah Hex star has announced that she is again planning to tie the knot with the former 90210 actor.

Her spokesman confirmed the news but did not give any details of when they plan to get wed.

Reports last week said the couple have bought a $2.9m mansion in Los Angeles.

Fox recently told Access Hollywood about their love: “I've been in this relationship for so long and I love [Brian] so much and of course [marriage is] in the future somewhere, I'm not closed to that idea.

"I just think, if you're going to get married, if you're going to be with someone and make a commitment, it's good to tell the universe, to say, 'I'm committing to this person and making them my family.'"
