Hip-Hop’s #1 groupie is at again. Apparently yesterday Kat got into a spat with NBA star Carmelo Anthony and his better half, La La Vazquez. Melo was far from mellow and reports are he lost his cool and put a 5 stacks hit on Ms. Stacks. Don’t think Commissioner Stern is gonna dig all this. The disgruntled Denver Nugget has since deaded his Twitter account. If the ref didn’t see it, is it still a foul?
