In this week's round-up of the Top Five Tweets of the Week, Diddy continues to ride the Charlie Sheen wave by joking that Sheen and his girlfriends will be the opening act for his Coming Home tour. Erykah Badu and fast food giant McDonald's surprisingly also poke fun at the Charlie Sheen drama with tweets referencing the actors recent statements. Meanwhile, pop singer Pink mocks Christina Aguilera's recent arrest for public intoxication. Then to wrap things up Bobbi Kristina -- the daughter of R&B singers Whitney Houston and Bobby Brown -- responds to photos released this week showing the 18-year-old allegedly snorting cocaine.
