The usually Bootylicious Beyoncé had jaws dropping at the Grammy Awards on Sunday evening when she sashayed the red carpet in a white and nude gown designed by Michael Costello, who has since revealed that the Drunk In Love singer is now a size 2 (UK size 6).
Her drastic weightloss has been put down to a 22-day vegan diet challenge she completed last month with her rapper husband Jay Z, and it seems that Beyoncé is embarking on another stint of the strict eating regime.

The 32-year-old shared a snap of a super healthy peanut butter and chocolate chip-flavoured vegan protein bar cut into chunks with slices of banana on top on Instagram on Wednesday.
The photo of the snack – which is free of gluten, soy and dairy – was accompanied by the caption: "#22daysvegan", suggesting that queen Bey is celebrating the success of her first diet by avoiding all meat and animal products once again.
Designer Michael Costello, who created her figure-hugging Grammys gown told E! News in an interview: "The dress was just made to fit a sample mannequin. It's smaller than a size 4. She is tiny! That dress is at least a 2/4.
He added, "She looks amazing. I just love the way it all came together."
