According to Daily Star, the 36-year-old British-Lebanese lawyer has started a healthy eating regime for the 53-year-old star, who has gained more than a 6kg since they tied the knot in September, in Venice, Italy.
"Amal told me there are five rules for George's new eating regime and healthy lifestyle that should get him back in shape as quickly as possible," a source said.
Amal Alamuddin is hoping George Clooney can shed the extra kilos before the Academy Awards on the 22nd of February.
"George is a pretty disciplined guy on set but, although Amal's new eating rules seem straightforward, he's going to find it tough because he loves Mexican food and even binges on the fast food variety several times a week in LA," the insider added.
"Rande Gerber and Cindy Crawford have promised Amal they'll do everything they can to help her get him back into some sort of shape before the Academy Awards," another friend said, adding, "But it's going to be tough as there's nothing George likes to wolf down more than a couple of spicy fish tacos followed by a shot or two of his own tequila."
