The holidays are already a stressful time of year so just imagine how Simon Cowell is feeling. The X Factor judge has one group remaining as we head into the two-part, four-hour season finale, and although Alex & Sierra look posed to win Season 3, Simon’s still worried the couple might fall short.

The snarky judge recently took to his surprisingly candid, personal Twitter to share his stress.

“I just had a nightmare Alex and Sierra didn't win X factor this week,” he wrote December 17, the night before the first part of the finale. Alongside the tweet: a photo of Simon’s adorable puppy dog, Squiddly, whom Simon credits as having the dream. Poor Squiddly looks totally bug-eyed and crazy after thinking A&S might not take the win.

Simon followed the tweet with a couple notes of encouragement from this week’s rehearsals.

“And on that note coming from rehearsals this is shaping up to be a great final,” he wrote. “There are three or four performances which are magic.” Based on his next tweet, it sounds like the majority of those magical performances are thanks to Alex & Sierra. “I think the songs by Alex and Sierra are perfect. And their duet spectacular.”

We’ve got no doubt Simon’s right based on how the pair of 22-year-old cuties has been performing during the last few Live Shows with their X Factor songs taking the top of iTunes two weeks in a row. So have a little faith, Squiddly. It was just a bad dream.
