Is Blake Lively pregnant?! We certainly think so!

The normally slim star was caught covering up her midsection while doing reshoots on the beach for her surfing thriller The Shallows in Los Angeles on Tuesday. And call us crazy (or totally right), but we are definitely able to spot a belly under all those layers. The leggy star usually has sleek physique -- so this bulky look is absolutely a transformation.

While some may think Blake is just covering up, we think this ensemble is a strategic maneuver to mask her growing belly. We here at X17 are basically professional baby bump spotters -- and we think that lady is knocked up!

We imagine it'll only be a matter of time before her people release a statement confirming the she and Ryan Reynolds are expecting baby No. 2. We can't wait to be right!

Blake is already the mother to 16-month-old daughter James, and has talked about wanting a brood of kids. Also, she's been out of the spotlight as of recently -- so in our estimation, it all adds up to her having a bun in the oven.

The Shallows hits theaters in two months -- so we're a little shocked that there are reshoots happening this late in the game. We also have a feeling the 28-year-old star wasn't planning on having to parade around her body on the beach, in front of film crew and the paps so close to the release date! Just an FYI: none of this bodes well for the movie. Reshooting two months before a film hits theaters pretty much means the movie is terrible.

Oh BTW and if you are thinking maybe her character is pregnant? Well that doesn't seem likely since The Shallows is about a surfer (with a super hot bikini body) who gets attacked by a great white and fights for her life. It's unlikely that screenwriters would throw in a pregnancy curveball into this shark vs. hot lady tale.

So basically what we are saying is -- Blake Lively is totes preggers and you heard it here first.
