Some apparently awesome photographer named Timothy White has taken some sexy celebrity photos for his new book, entitled Hollywood Pinup.

Among those featured is the beautiful Kate Walsh, 40, who used to star on Grey's Anatomy before moving on to mediocre spin-off Private Practice.

Yowza. We wouldn't mind having to Practice some very Private things with Kate Walsh if you know what we mean. We're talking about ... forget it.

Enjoy the photo:

HOLLYWOOD PINUP: A sexy Kate Walsh certainly looks the part of the new book she's in. How that guy talked her into this, we have no clue. But awesome work.
