The source told The Sun newspaper:
"Nicole has seen most of the girls on and off over the years and she's ready to get back together.
Rather than trying to patch up their differences, it's more about working out how to get everyone in the studio and see what it will actually sound like.''
The news comes after the 37-year-old star - who had hits such as 'Don't Cha', 'Buttons' and 'When I Grow Up' with the group - recently teased she would like to get back together with the Dolls.
Asked about the possibility of a reunion, she said:
"I don't see why not. I miss it. I miss the girls.
It was such a crazy time for us that stepping away from it now and taking some time away from it I'm like 'I wanna be able to do it again and really enjoy it and take it in and enjoy the travels with the girls'.
