Whose a-squeezing?Whose a-squeezing?Coo-ee, things are getting a little hot under the collar here.

It seems as though there's a bit of girl on girl love action going on.

Crikey, it's Sharon Osbourne, having a go at Anastacia's fun bags.

Why on earth is she wrapping her perfectly manicured talons around those puppies?

The two got up close and personal at the Frosted Pink fundraiser in LA.

Both have battled cancer, and are now doing their bit to raise money for the cause.

The invitation to the event read: "Help us squeeze money out of guests for breast cancer."

But we're not sure they meant that literally, Shazza.

Not that Anastacia looks too unhappy about the whole affair.
