It's National Cleavage Day, so what perfect excuse for some of our boobiest celebs to get them out and post pictures of themselves all over Twitter?

But seeing as two of those celebs in question didn't make the top 10 of this year's Wonderbra Cleavage Hall of Fame, perhaps they are launching their appeal to take home the crown next year?

First up was the ever shy and retiring Jodie Marsh, who tweeted a picture of herself wearing, well not very much at all, obvs.

"If it really is #nationalcleavageday then here's mine ;-) x x x," she tweeted.

She then promised to post old pictures of her most famous looks every hour to celebrate the event.

The next one read: "Another pic for you for #nationalcleavageday with my#bestbubbles," she tweeted.

We're still unsure if #bestbubbles refers to her pals or her breasts.

Moving on...

Imogen Thomas also got in on the action as she posted a pic of just her boobs in a red bra, but obviously became a bit embarrassed (first time for everything) and took the snap down.

"Happy cleavage day! Mwah :-) xxx," she tweeted.

National Cleavage Day is an annual celebration created by Wonderbra as a day of appreciation for breasts in all shapes and sizes.
