Did Beyonce just reveal she's pregnant?

Did Beyonce just drop some big news from the beach?

The Grammy-winning singer shared an Instagram photo on Sunday that has fans wondering if she's pregnant with baby No. 2.

In the snapshot, the 33-year-old singer is seen buried under a mound of sand that looks a lot like a pregnancy bump. Daughter Blue Ivy, 3, appears to be playing at her side.

This isn't the first time she and husband Jay Z have been the subject of speculation about a second pregnancy. Back in September, the rapper sparked baby rumors during a performance in Paris when he changed lyrics in his some "Beach is Better" from "replace it with another one" to "pregnant with another one."

The photo has no caption, but Beyonce has been known to drop bombshells with little to no warning -- like revealing her first pregnancy on the VMAs red carpet or the release of her surprise self-titled album back in 2013. So if this is indeed a pregnancy announcement, it seems that Blue will be a big sister pretty soon.
