Kate Middleton pregnant again!? Duchess sips wine as Prince William drops baby bump hint, 'another son coming soon?' [PHOTOS]

Is Kate Middleton already expecting baby number two?

According to Prince William, maybe!

The Duke and Duchess of Cambridge have kept very busy in New Zealand over the past week. Still no signs of a growing baby bump, but William hinted that there may be another royal tot on the way very soon!

Cynthia Read, a 61-year-old woman who was commisioned by the New Zealand governement to make a shawl and present it as a gift to young George, said the future King replied with this hint when handed the frock:

"You might have to make another one soon." 

Read told reporters on Saturday (April 12), "The way William said it was like he was dropping a hint... letting me in on a secret." 

So, does Read think Middleton's actually preggo?

"Maybe. I couldn't possibly comment! Obviously if I'm asked to do another one, I would be honoured, but we'll wait and see." 

It took Read four months to sew the wool together for baby George's white, fern-patterned shawl (designed by Margaret Stove). According to Read:

"Kate told me they were really happy with it and George wore it a lot. She said it was so lovely and soft. They have brought it to New Zealand and he is wearing it, but she apologised for not, so far, finding an appropriate event outdoors to wrap him in it."  

But here's the thing - Middleton was spotted sipping on some wine while touring Amisfield Vineyard's in Australia!

According to wine expert Jared Darby (who took the couple on their tour):

"The Duchess did take a little sip, but I don't think she's a big drinker. We nearly moved on without the Duke or Duchess having a glass of our wine, but [William] was keen to try it. He said, 'Hang on, let's enjoy a glass of wine. We can't pass up the opportunity.' [They] both picked some grapes as we were walking through the vineyard and William in particular seemed to know about red wine -- I think that's his favorite" (via Us Weekly).

Onlooker Hannah Armstrong also revealed:

"Kate said she hadn't drunk whilst pregnant with George and although she doesn't drink much she was really enjoying the odd glass."

Meanwhile, reps for the royal family have declined to comment on such viral baby bump rumors.

So - maybe not pregnant? Perhaps very soon though!
