Despite a lot of criticism today about cutting her hair to look like Miley Cyrus (left), personally I think Pam looks great. I'm not sure if that's a very tight top she's wearing but those are definately smaller boobs. Maybe she's gone with small implants or actually had them removed, I wonder what they look like now after years of holding implants?
If you do a little research (google it) you'll see that way back at the beginning of her modelling/TV career she had B cup breasts. See below video.
