Kelly Osbourne is unhappy with her shrinking breasts.

The 'Fashion Police' host used to be a DD cup size during her younger years and she is dismayed that her boobs have dramatically reduced to a size B.

Kelly wears Wonder Bras to give her bust a boost but she is worried her boobs are getting even smaller.

In a series of tweets on twitter, she wrote: ''Why do they call it a Wonder Bra? I think its cause when its off you 'wonder' where your boobs went! How is it I was DD at 18 & at 27 Im a B?

''Off to the g maybe my empty sacks of s**t that I call t*t's will get even smaller! #awesome (sic)''

Kelly is not the only star to have boob issues after Jennifer Love Hewitt recently revealed she has been having bad dreams about people trying to ''deflate'' her 36 C breasts.

She said: ''I actually had a nightmare the other night that people were trying to deflate my boobs while I was working. They had tubes and I was trying to work, but they kept getting smaller.

''I was like, 'Guys, don't take them away!' I'm getting issues about it, I think.''
