Beyoncé just dropped a serious pregnancy hint on Instagram!

Speculation has been rife for months that a second baby could be on the way for Beyoncé and husband Jay-Z, and if this latest Instagram snap is anything to go by, the couple could definitely be preparing for a new arrival!

The superstar family are currently on holidays in Southeast Asia, and Bey has been been sharing some gorgeous pictures of the trip so far – including a picture yesterday of the singer buried under a pile of sand moulded to look like a pregnancy bump.

Some innocent handiwork by Blue Ivy, or Bey's way of hinting that she is expecting again?!

Fans were quick to make reference to the obvious bump, with comments like, "Bey, just stop it and say you're pregnant with baby #2, i cant with these hints. I want BlueBlue to hav a sibling alreadyy [sic]." Yup, that's pretty much our attitude too!

Whether some big news is on the way from Beyoncé remains to be seen – this isn't the first time she and Jay-Z have set the rumour mill off. Back in September, Jay-Z altered the lyrics of his song Beach Is Better during the couple's On The Run tour, singing, "cause she's pregnant with another one" to an audience in Paris.

Five months on, there's still been no word, so we're guessing that was just Jay-Z's way of messing with our heads, the scamp!

With Blue Ivy having just turned three, the couple have spoken openly about wanting a larger family. During her first pregnancy, Bey said she wanted to complete her brood by the time she turned 40. "I have always said that I want to have all my children by the time I am 40, so there's still a lot of time left… There is an attraction for sure about having a large family, but we will just have to see what we are blessed with," she said at the time.

Well Beyoncé turned 33 in September… so that's seven more years of rumours to go!
