Beyonce flashed her toned tummy in the second week of the 22-day vegan stint she's undergoing with Jay Z, sharing the evidence on her Tumblr

Beyonce is one full week into her attempt at going vegan for 22 days.

And it seems the singer is feeling good about her health kick; on Tuesday she uploaded a series of bikini-clad snaps for her fans via social media.
The gorgeous 32-year-old also posted a touching snap of herself playing hide-and-seek with daughter Blue Ivy, who turns one in January.

Well, something's working! Beyonce flashed her toned tummy in the second week of the 22-day vegan stint she's undergoing with Jay Z, sharing the evidence on her Tumblr

In the series of photos, Beyonce poses in tiny white bikini bottoms and gives a nod to her home state in a red Texas football jersey, rolled up under her bra to reveal her flat stomach.

The star's body appears completely flawless in the snaps, with evidence of solidly toned abs in clear view beneath the jersey.

With her highlighted tresses out and flowing in beachy waves and zero makeup on, she shows off her true natural beauty in the candid photos.

Later, Beyonce got a little kooky and slipped a giraffe hat on her heat to add some obscurity to the mix and perhaps to give a shoutout to the animals she's caring for in her brand new vegan diet.

In another photo, the stunning mother sits on a floor with her daughter Blue Ivy, and giggles as she jokingly hides the little one's face with a large straw cap.

And in yet another snap added to the same series, Beyonce shoots the camera a cute and enigmatic gaze in a black and yellow striped maxi dress, as she stands next to some tropical plants.

The selection of snaps came just one week after Jay Z revealed that he and his wife were inspired by a close friend to give up animal food products until December 25.

The Holy Grail hitmaker wrote on his Life and Times Blog on Tuesday: 'Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way.'

'On December 3, one day before my 44th birthday I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based!'

Cute: The star put on a surprised expression for the happy snap which she shared with her adoring fans

'This all began a few months back when a good friend and vegan challenged me to embrace a plant-based breakfast everyday. It was surprisingly easier on me than I thought.'

He added: 'It just feels right! So you can call it a spiritual and physical cleanse. I will post my progress. Any professional vegans out there that have any great food spots please help out! Please!

'I don't know what happens after Christmas. A semi-vegan, a full plant-based diet? Or just a spiritual and physical challenge? We'll see. P.S. B (Beyonce) is also joining me.'
