Jade.. shipshape & Bristols flashin'.
First the gobby celebrity, who recently splashed out pounds 4,000 on new 36DD boobs, stripped off her bikini top.
Then, all shipshape and Bristols flashing, she and a pal held hands and jumped off their boat.
With her new top-heavy shape, the former Big Brother star dropped like a stone.
She hit the Mediterranean sea much faster than her skinnier shipmate.
But thanks to those big bouyant boobs, there was little chance of Jade going under.
And she was soon doing the breast stroke in the warm water.
One onlooker said: "Jade bounced straight back up again and you could hear her loud cackle as she surfaced.
"She obviously enjoys showing off her new figure and doesn't care who sees it.
"But the funniest thing was that all the rest of Jade was wobbling except those boobs.
"They stayed so upright they looked like they had been moulded out of plaster."
Mum-of- two Jade, 25, joined a bunch of mates on a hen party weekend in the Spanish resport of Marbella. They took part in water fights, drinking and dancing competitions.
And Jade couldn't stop giggling after they chartered a boat called Black Pearl - the same name as the vessel in the hit film Pirates of the Caribbean.
Our source said: "She looked like she didn't have a care in the world."
Jade has become a millionairess since joining the Big Brother house in 2002.
After her new boob job, she is now planning a tummy tuck.
For the moment, though she is obviously having the breast days of her life.
