Why does Vanessa Hudgens need a pregnancy tesy kit

Vanessa Hudgens was spotted in Boots Pharmacy in Hunslow, London buying a pregnancy test. She could be pregnant but is not confirmed.

This just came in and theres no proof to the hearsay that is happening in the internnet. Speculations are just speculations unless otherwise we see a baby bump or admittance from "Van" that she is indeed pregnant, and if she is, who could be the father. It better not be her ex-boyfriend Zac for they have parted ways long ago. and if it's not Zac who could it be?????

You be the judge
