Beyoncé Knowles Instagram - Queen B's latest Instagram post has got the whole world talking. The mother of one recently shared a photo of her lounging in the beach. Yet, the obvious part of the photo where she's stuck in the sand is a protruding belly. Is this a hint at Beyoncé's second pregnancy?

Now that Blue Ivy is three years old, it's about time Beyoncé and Jay Z work on another addition to the family. Well, this is what half of their fan base think. However, the latest post on Beyoncé Knowles Instagram might have already shown that the couple are one step ahead.

Early in Sept. Jay Z had hinted at his wife's second pregnancy. The rapper changed the lyrics of his song mid performance during their summer tour. The lyrics go: "cause she pregnant with another one." In May 2013, rumours of Beyonce's second pregnancy were also high after a fan posted a photo with Beyonce's baby bump seemingly obvious.

Looks like they're stirring the rumour pot once again with Beyonce Knowles Instagram post. The 33-year old songstress posted a snap of herself covered in sand, which ironically shows her with a baby bump.

Followers of the stars have commented on the photo asking if she's pregnant. Apart from Beyonce Knowles Instagram post that hints at her second pregnancy, the singer's outfit for her Cambodia trip certainly say a lot. Beyonce has been parading around Angkor Wat in loose outfits. Is this an effort to hide the growing baby bump?

The couple have been married since 2008 with Blue Ivy as their first child. Both have been pretty vocal about adding more to their family. Representatives of both Jay Z and Beyonce have yet to comment on the reports about the second pregnancy. Right now, fans can only depend on Beyonce Knowles Instagram for all the latest updates.
