Bruceypoo! That's not very nice!

On Saturday afternoon Bruce Jenner ran errands with daughter Kendall, and after switching cars, a photographer asked the 64-year-old reality TV star how he was doing. Bruce yelled, "Go f*ck yourself!" and as he walked by another pap, he gave the lensman a shove and said, "And you can go f*ck yourself too, buddy!" MEOW!

On Friday afternoon we caught Bruce paddle boarding in Malibu ... maybe he was still sore from that? He didn't look like he was having the easiest time in the ocean...
