"Dina is still working on the date of the party but it's looking like towards the end of the year," News of the World quoted a source as saying.
"Lindsay's new album Spirit In The Dark is out in November, so I wouldn't be surprised if it's around then.
"They've been keeping the relationship quiet for months and trying to pass each other off as 'just good friends'.
"But they've decided it isn't a fling, it's for life- so they want to make their romance public," the source added.
