Did Felicity Huffman really hit 11-year-old Rachel Fox while shooting last Sunday’s episode of Desperate Housewives—and will the slap come back to haunt her during the upcoming two-hour season finale?

Either way, Rachel ain’t spillin’.

But no need to call Child Protective Services. It was all part of a day’s work when Huffman’s Lynette Scavo smacked her evil stepdaughter, Kayla, played by Rachel.

When I asked Rachel this morning just how real the slap was, she laughed, “Did it look real to you?”

When I told her it did, she simply said, “Good.”

And that's not the only thing she's clamming up about...

She’s also under strict orders—just like the rest of the cast and crew—to remain tight-lipped on the finale.

How difficult has it been to keep it to herself? “Oh my god, it’s harder than you can imagine,” Rachel said. “It’s like choosing between chocolate ice cream and vanilla ice cream.”

Housewives isn’t the young actress’ only project at the moment. She just shot a music video for a song she wrote called “i Shop.” Yep, Miley Cyrus is one of her idols.

“I’d love to have my own show and be a singer, too,” said Rachel, who appeared in an episode of Hannah Montana as one of Hannah’s biggest fans.

Rachel hasn’t seen Cyrus’ controversial Vanity Fair pic, though. “I just hope the best for her because she’s a really sweet girl,” she said. “She’s a really nice person, so inside I know she’s good.”
