Tabloid magazines are on Kate Middleton overload this week.

As the public and the royal family are still reeling from photos published showing the Duchess of Cambridge sunbathing topless, another gossip outlet has reportedly doctored a photo to make Middleton look pregnant.

Star Magazine's latest cover pictures Middleton with what appears to be a baby bump. The headline reads: "Scandal turns to joy: It's Twins!"

Below the headline is a further explanation of the story Star reported, which reads, "Pregnant Kate gets thrilling news amid nude-photo uproar."

But doubts have surfaced online about whether the photo is real or if it has been altered. A comparison of the Star cover and the original photo shows several key differences that suggest something has been changed.

Middleton's midsection looks larger in the Star cover photo, and her floral dress appears stretched. Other small yet noticeable differences include a change in the angle of the glass Middleton is holding, the ring on her finger being removed and the head of a woman in the background disappearing.

The possible doctoring of the photo comes amid continuing controversy surrounding the topless photos of Middleton published by French magazine Closer. Kate and husband Prince William recently got away from the chaos by taking a "second honeymoon" in the Solomon Islands.
