It takes two: Beyonce held up two fingers to the camera in an Instagram shot  posted in December which many fans saw as a cryptic signal that she is expecting twins

Following Beyonce's pregnancy announcement on Wednesday, fans have been quick to jump on the December shot, with some speculating they can see a small baby bump, while others take her two finger salute as a sure signal for twins. 

One fan speculated: 'I didn't pay attention until now. And the peace sign must've been a hint at the twins. She's the queen of hidden messages.'

Another excitedly commented: 'So it wasn't a peace sigh, it was a two babies signal,' while a third fan was wrote: 'OMG is it just me or can you can actually see a baby bump.' 

'Bey giving hints the entire time,' sighed another Instagram follower.

 'She was hinting back in December!' another fan claimed, while another wondered if they could see a bump under the singer's dress, adding 'she might be due April.'

'You can KIND of see that blue dress has a low bump facing the front,' one wrote. 'I don't know about the side view though.'

Meanwhile, it seems the singer's pregnancy was even a surprise to her own father.

Matthew Knowles revealed to The Insider that he learned the news along with the rest of the world. 

'I was shocked,' he told the U.S. website. 'I got a first text, and I was like, "Why is this person saying congratulations?" Then I get a second text from one of my students at Texas Southern, and I was like, "What are you talking about?" He was like, "Go to the web." I didn't know myself.'

However, Matthew has since spoken to the singer, revealing he thought she sounded weary after rehearsing for her Grammys performance.

'She sounded a little tired ’cause she’s been working on the Grammy performance,' he said. 'We just had a wonderful daughter-dad conversation.'

Beyonce has certainly made the most of her second pregnancy, posting an array of eye-catching images on her website.  

On Thursday the singer's website was awash with images of her showing off her baby bump, along with throwback snaps of her daughter Blue Ivy when she was a newborn.

Included in the collection were some artsy underwater GIFs showing the Drunk in Love hitmaker wrapped in colourful strips of fabric as she displays her burgeoning tummy.
