Bruce Jenner grabbed coffee bright and early this morning, and while he didn't yell at our photographers, the reality TV star, who has confirmed that he'll be transitioning from a man to a woman, was incredibly grumpy. Hey, it's Monday -- and Bruiser hadn't had his coffee yet, so we totally understand!

In other news, there's a new report that Bruce has known since he was just five years old that he wanted to be a woman! Family sources tell TMZ, when Bruce had his big pow wow with the family earlier this year, he revealed that he's been keeping "true self" inside since he was a child. And get this -- during the '76 Olympics, "in his head he was a woman." The website also reports that Bruce has "never been female" in front of any of his kids.

Until now!
