Charlize Theron is content with being a single mom-of-one, but sometimes she thinks about adding to her tiny brood.

The actress, who adopted son Jackson last year, admits she's considering having more kids -- under one condition.

"More?" she questioned as E! News asked the "Mad Max: Fury Road" star if she was interested in expanding her family. "I don't know. I mean, if all my kids could be like Jackson, I'd have 10 more right now."

If it were up to Theron's mom Gerda, her daughter would already be pregnant and/or starting the adoption process.

"I'd love her to have more," Gerda chimed in while Theron laughed and added, "She's always asking me when."

One thing is for certain though -- Theron's short hair is staying.

"It's so low maintenance," she said, "and having a kid, you need as much time as you can get."
