Jay Z is reportedly keen for Beyoncé Knowles to put on some weight.
The Drunk in Love singer and her music mogul husband embarked on a 22-day vegan diet at the end of last year, which saw Beyoncé slim down to a tiny UK size 6.
She showed off her amazing weight loss at the Grammy Awards in January, but Jay Z is said to be keen for her to get back to her 'bootylicious' self.
"Jay wants her booty back," a source told British magazine Heat.
"He's always loved a woman with a big behind, and as hot as his wife is right now, with her super-sexy dancer's body, he much prefers Bey when she's got curves. He's told her that she looks mind blowing but he can't wait for her to get her butt back."
Beyoncé and Jay Z welcomed their first child, daughter Blue Ivy, in January 2012.
It didn't take her long to lose the baby weight, but Beyoncé's husband apparently thinks a gain of 7lbs. would be perfect for the star.
"It's all down to the 22-day vegan cleanse - Jay hated every moment of it but Bey totally embraced it and loved the results," the insider continued.
"She wanted to prove that she can still shake her post-baby body with the best of them and loves the reaction. Plus, Beyoncé wants her body in optimum shape for her forthcoming tour dates."
The Mrs. Carter Show World Tour embarks on its Europe leg from February 20.
While Jay Z is thought to be keen to expand their brood, the gorgeous singer is apparently more focused on work right now.
"She would love to try for another baby - but not till after the tour," the source finished.
