Kate Middleton is involved in yet another photo scandal, where the Princess is pictured  in a two piece blue bikini on Chi bikini.

Showbiz Spy reports: Aussie magazine Woman’s Day and Italian tabloid CHI have both published photos of the British beauty — who’s expecting her first child with husband Prince William — looking very pregnant during a stroll along the beach while on vacation in Mustique.

But how are the paparazzi finding out where they are?

Well, one insider has alleged Kate has actually been tipping off the press.

“It’s her way of controlling what pictures get out there,” a source claimed. “She learned her lesson from the last time, when those topless pictures leaked…

“She knows the press want [provocative] photos of her, so her team let a chosen group of snappers photograph her so she can control what gets out there. It’s very clever!

“And if you think this seems strange, remember the deals the Royals make with the media when Prince Harry goes to Afghanistan.”

Meanwhile, other insiders have alleged there’s a spy lurking in the midst.

“Kate and William are paranoid there’s a spy in the palace who’s giving away their secrets,” an insider said “So much has been slipping out that it can’t be explained as coincidence.”
