Hilary Duff is spending some time in San Francisco with her mom and sister.
On Thursday Hilary tweeted:
Heading to mystery city with moms today! I bet this is when the baby shopping begins! Oh dear... Thank god the hubby's out of town!
Then on Saturday, Haylie tweeted this picture of the three getting ready to go zip-lining:
