Selena Gomez is on her grind these days. Should Rihanna be worried? Should Miley Cyrus? Should Kesha? Well Kesha is garbage but should the rest of them??

Look out Justin, Selena is on her her G.R.I.N.D. Get ready its a new day. So if she keeps getting bigger is Beiber gonna get jealous and go all Chris Brown on her? Only time will tell. And maybe Miss Cleo, lawd a mercy!
