Katie Price has been warned that her surgically-enhanced breasts could explode or drown her if she goes ahead with a diving course, according to a report.
The glamour girl is currently enjoying a holiday in the Egyptian resort of Sharm el-Sheikh with husband Alex Reid and her eldest child Harvey, 7.
Earlier this week, insiders claimed that Price wanted to go diving in the Red Sea as part of the break.
However, a source told the Daily Star: "There have been scare stories about implants exploding underwater.
"Research has shown this is unlikely but they do fill with air bubbles as the pressure increases and can change size underwater. Implants also affect buoyancy so she'd have to make extra efforts to stay afloat.
"Given the risks, and how long she has spent perfecting her boobs, it is unlikely Kate will go ahead."
Earlier this week, Price announced that she had pulled out of this year's London Marathon on medical grounds
