Rebecca Loos Come in the coastguard, we have a pair of ocean boobs on the loose.

We repeat, someone's breasts are trying to be as free as Willy the whale.

Yes, Rebecca Loos seems to have lost her bikini top.

She's had a mammary moment while holidaying in southern France.

And being topless doesn't seem to be bothering her in the least.

But Ms Loos isn't the only star whose bra friends like a bit of air time.

Oh no.

More than one star has feared to go where many other bare boobs have gone before...

And put them on display.

Meet Rebecca's topless pals in our gallery.

Let us warn you though, there is a lot of flesh on display, so don't click if you don't want to see it.
