Is Suri going to be a big sister?

Those knowing glances....those protective hands on the tummy...that cheeky "I-know-something-you-don't-know" smile....if it turns out to be true, you heard it here first....
PS: If Katie Holmes is pregnant, we hope it's another little girl...Suri has PLENTY of gorgeous dresses, shoes, coats & accessories to hand down to a little sister. Plus, it is so much fun having a little sister, just ask Gigi & Lulu...x
