Terry McMillan is getting ready to re-introduce movie audiences to beloved characters Savannah, Gloria, Bernadine and Robin in the sequel to “Waiting to Exhale.”

The author, who spoke with ESSENCE.com during the ESSENCE Music Festival, says she’s working on the third draft of a script she hopes will be complete by the end of July. “This won’t be on the screen until sometime in 2012 though,” she warns.

McMillan broke the story on Twitter a few months ago, tweeting, “We are working on the script for ‘HAPPY.’ Will know in about a month or so when we’ll begin production.”

Asked whether she thinks Whitney Houston, who is currently in rehab, will return as Savannah, McMillan says she is “hopeful.”

“We’ll know soon enough,” she said. “I’ve been told that’s she wants to do it, and I think the studio wants her to do it. We all want her to do it… I just hope she’s healthy.”

We do too, Terry. Can you imagine the girls back on screen together? Bliss!
