The female half of X Factor Season 3 duo Alex & Sierra, Sierra Deaton seems like one of the most talented, most bubbly ladies to ever grace the X Factor stage. But it turns out this 22-year-old California girl has a secret.

She hiccups. Like all the time.

In an exclusive interview with Wetpaint Entertainment, Sierra spilled the beans about her distracting little habit. “I hiccup like 30 to 40 times a day,” she says, adding it’s a result of an overexcited stomach. “It’s just something I’ll always have.”

Hiccuping that much would be pesky for the average Joe, but for a musician? Doesn’t it get in the way of her X Factor performances? Well, not so far, says Sierra.

“I might have done it on the show but the camera’s never been on me,” she says. Whenever she feels a little hiccup coming on she’ll step away from the mic and hope it wasn’t caught on camera. “It’s never an issue,” she adds with a laugh.

We doubt even a little spare gas could stop Alex & Sierra at this point. The pair of singing lovebirds claimed the top spot on the iTunes singles chart last week and look primed to take a spot in the Top 3. Let’s just hope extra nerves don’t mean extra hiccups.
