Jenna JamesonWhose B'Day Treat?Somebody has been a thoughtful girl.

And made a v big effort for her man's birthday.

A card and a pressie simply would not do, to celebrate this blokes 33rd day of birth.

So she held him a mahoosive bash to celebrate instead.

And it doesn't end there.

Guess what was the main event...

Well it was this celeb lady, somewhat scantily clad - as you can see.

She popped herself from a cake.

And did some singing and a-shimmying in her smalls.

For him and all his guests to see.

But who is this brave lass?

Let's put it this way, she's no shrinking violet.

Put a name to the pants in our pics of whose birthday treat?
