Who's this?Who's this?We'll give you a clue. It's a woman playing a man who's dressed as a woman...

Confused? Here's another one. She's Wisteria Lane's most harassed housewife.

Yes, it's Desperate Housewives star Felicity Huffman in her new film Transamerica.

The Emmy-winning actress plays a character called Bree in the film, a pre-op male-to-female transsexual.

By all accounts, she really did all she could to feel her way into the role.

According to Heat, she wore a prosthetic penis to help her think herself into the, ahem, part...

And she even christened her extra 'limb' Andy.

She said: "Towards the end of filming, I walked into the ladies' room and went, 'Wow, I'm not supposed to be here,' and I walked out... Then I said, 'Oh no, I am,' and walked back in again.

If she can manage to fool herself, then it's no wonder she's already bagged the odd award nomination for her portrayal.

We look forward to seeing Felicity's (and Andy's) work.

Wonder if she kept him?
