The defender has signed on loan from Everton.
Brougham came in at Blues last season on loan from the Toffees in January.
She made four appearances - two apiece in the WSL and FA Cup - before the season was halted due to COVID-19.
Brougham's addition to the ranks will help strengthen Carla Ward's backline options.
The Head Coach commented: "Georgia comes with a lot of experience, despite being young. She has played at the highest level now for a number of years.
"I think what is important too is just how well she settled into the group when she came after Christmas. And the girls have got a lot of respect for her.
"She slots straight into what we are trying to do, the way we want to play."
Brougham, 24, came through at Manchester City before switching to Everton, whom she helped win the FA WSL2 Spring Series in 2017.
Ward said she was happy with the personnel now at her disposal defensively.
"We knew straight away that we needed one or two players - maybe even another one on top of that.
"But I like to play wide players as full-backs, that's the way I work. So, yes, I'm happy certainly with the options we've got."
