She's usually surprising audience members with unexpected gifts on her show, but Ellen DeGeneres recently gave her wife Portia de Rossi a shock.

Sharing it all in a segment titled Celebrity Christmas Stories, the affable host explained, " 'I got her a car. That was easy. But I had to hide it in the attic...which was not easy. It was a car she really, really wanted and was obsessed with this car. It's pretty rare.

Setting the scene, the 55-year-old comedian begins, "So there is a car called The Defender, and there aren't a lot of them, and every time she sees one, she says 'I love that truck. I love that it is so cool.' But they are hard to find. I found one in Texas. I had it trucked in and I parked it in a shopping area I knew we were going to go shopping in later that day and had the bow on it. So we were walking and I knew she would notice it, so I filmed it with my phone."

Spotting the vehicle immediately, the "Arrested Development" star asks, "What about that car, did you get me that for Christmas?" Upon seeing Ellen with a keys, the shocked actress exclaims, What, are you kidding?" Check out her reaction in the player below.
