Picture: Lifetime/Grumpy Cat's Worst Christmas Ever via YouTube Source: Supplied THE trailer for Grumpy Cat's new anti-Christmas movie has finally dropped - and the world's crankiest internet kitty is armed and dangerous. Grumpy Cat's Worst Christmas Ever follows a 12-year-old girl who asks for a special friend for Christmas. Her wish comes true - in the form of Grumpy Cat. The internet sensation - real name Tardar Sauce - is voiced by the hilariously deadpan Parks and Recreation star, Aubrey Plaz. Unsurprisingly, Grumpy Cat hates everything about the holiday season - calling her new owner a "blonde witch," firing a paintball gun and verbally abusing other cats. REALLY ANGRY: Grumpy Cat gets her own feature film Grumpy Cat's real-life owner, Tabatha Bundesen, says her permanently scowl is due to feline dwarfism and an under bite. But unlike the memes she has inspired, the kitty is actually very nice. The pernicious pussycat has more than 6.8 million likes on Facebook and 16.3 million YouTube subscribers. Grumpy Cat's Worst Christmas Ever premieres in the US on November 29. Honest memes ... Grumpy Cat hates everything, including purring. Originally published as Christmas can't cheer up Grumpy Cat
