Louise can do one. Judging by Zoe's due date she's just at the 12 week stage which, even though it's generally considered the 'safe zone' for announcing a pregnancy, is still a precarious stage where things can go wrong. What if Louise brought all that speculation Zoe's way and then - heaven forbid - she'd had a scare or worse? I really hope Zoe announced the pregnancy because she was ready and not because she felt as if she had no choice. I certainly wouldn't be sharing anything with Louise in the future if I were her.
