How do you know? I mean it definitely looks like her, but has anyone ever been able to verify that these pictures are actually of her?

I don't think it's really her. True there is a strong resemblance BUT there is one important thing different:

In every episode i can remember, and every picture i can find on the official real world website...

Melinda wears a ring on her right hand.

These could possibly be older pictures... who knows, people take off their rings once and awhile.

good one dude.........

whoever she is very hot thanks

Can I verify with a cerificate of authenticity it's her? No. The information I've found says that these pictures were taken at a Maxim hometown hottie contest/party in 2004 at a club called 1225 Water.

Hmmm
 

I'm not complaining, mind you, but that's a lot more than a nip slip!
