Washington, Feb 6 : After baring their body-painted breasts at the Super Bowl bash held at Playboy mansion, Hugh Hefner's twin girlfriends are rumoured to be considering going under the knife to enhance their twin assets.

A source has revealed that at least for some time, the 82-year-old's twin girlfriends will remain natural, and not go for the traditional playboy image of extra-busty females.

"Hef really likes them as they are and so far no plans for surgery have been put in place," Fox News quoted an inside source as saying.

The insider added: "It could just be a matter of time, but as for now they're content being natural."

However, another person close to the men's magazine mogul thinks that their lack of silicon is already ruining reputations.

"They're A's and they're representing Playboy, ridiculous," said the source.

The Playboy mogul has happily paid for his lovers' surgery in the past. (ANI)
