Beyonce is not happy with speculation about a bun in her oven, and she took to Instagram to say so.

When sources confirmed yesterday that Queen Bey and Jay-Z were expecting another heir to their hip-hop throne (not to be confused with the Throne, which Hov shares with pal Kanye West), Bey was furious. She posted a missive on the photo sharing site that read:

I can't stop the rumors from starting, and I really can't change people's minds who believe them. All I can do is sit back and laugh at these low life people who have nothing better to do than talk about me.

The image has since been removed from Beyonce's account, but screenshots -- much like the unflattering photos of her Super Bowl performance -- are forever.

Sources close to Beyonce previously scoffed at the pregnancy rumors, but where there's smoke, there's usually fire -- and her cancelled concert in Antwerp, as well as her emotional streak onstage, strategically fitted Met Gala gown and perceived pics of a tiny baby bump may be stoking the flames.

Beyonce's response garnered her quite a bit of criticism before she erased it, but when you look at the singer's history, it makes sense that she'd be defensive. Bey has always been fiercely private about her personal life, and considering she previously suffered a miscarriage, she's likely much more protective and secretive about any potential pregnancy -- especially in the fragile early stages.

Still, it appears an official confirmation is looming, considering Bey didn't exactly deny the news. Time will tell!
