Now that she's a host on "The X Factor," Khloe Kardashian is inevitably going to face questions about singing. On "The Tonight Show," Jay Leno asked her if she had any singing ability, and she was quick to say that she didn't.

But it wasn't an innocent question. It was a set-up so Leno could show a home video of a very young Khloe ... singing?

"That’s 'Happy Birthday to You'?" her father, Robert Kardashian, could be heard on the tape asking after Khloe's performance.

Inevitably, though, the conversation shifted to Khloe's sister Kim, and her beau Kanye West. The couple recently took in a taping of "The X Factor" and Leno wanted to know if Khloe thought West might one day be her brother-in-law.

"There’s a chance for anything," Khloe said.

Catch Khloe Kardashian most assuredly not singing as a co-host on "The X Factor," Wednesdays and Thursdays at 8 p.m. ET on Fox. "The Tonight Show with Jay Leno" is on every weeknight at 11:35 pm. ET on NBC.
