The Mr and Mrs Smith actress, in an interview with Marie Claire magazine, reveals that the easiest way her beau can get her talking, is by getting into the tub with her while she's relaxing after a long day's work.
She also reveals that she somehow finds it easier to open up when she's not wearing a stitch of clothing.
"I don't know how he does it, but... I talk a lot in the bath," People quoted her, as telling the magazine for its July issue.
"It's easier to talk when you're naked... Get naked with me, and I'll talk!" Jolie adds.
Jolie also gushes about her beau's parenting skills, and admits that she just loves seeing the relationship Brad shares with the kids, especially oldest kid 5-year old Maddox.
"I'm so happy for my children – especially Mad. I didn't know if he was ever going to have a dad. So when I watch them having real strong father-son time, or even when Mad tells me, 'This is a boy thing, Mom' – it's just really beautiful to see," she says.
As for her own relationship with Brad, Jolie says that their connection has grown over time, and that they are ‘lucky' that they turned out to be right for each other, especially since their family has grown so quickly over the past two years.
The couple, who met on the sets of the 2005 film Mr and Mrs Smith, embarked on a relationship after Pitt's divorce to former Friends star Jennifer Aniston came through in March 2005.
"I think we both went on a lot of faith – we really did. Our family has grown very quickly, and we have a lot of responsibility together, and we acknowledge that we are lucky we turned out be for each other everything we'd hoped," she says.
"We could have been very wrong, but every challenge we hit has brought us closer. It has been that kind of relationship," she adds.
