Celebrating the holidays for the first time as a couple can be a stressful situation – a bad gift or the wrong word spoken to a family member can be a passion killer.

Luckily for Kaley Cuoco and her fiancé, Ryan Sweeting, their first Christmas together was just perfect.

The Big Bang Theory star posted a pic on Instagram that shows her looking a little surprised that things went so smoothly. "1st Christmas together!" she wrote. "Killed it!"

Cuoco has every right to raise a glass in a toast, as she nailed it when it came to giving out gifts. The 27-year-old gave her parents a Lexus!

While we don't know what she gave her husband-to-be for Christmas, he did post a pic showing how impressed he was by her ability to find the perfect presents for her loved ones, calling her "Santa Kaley."

The couple, who got engaged in September, after only dating for a few months, are set to wed on New Year's Eve.
