KIM K AND KANYE ENGAGED?

 The reality TV star was spotted wearing a huge sparkler on her pinky finger while filming her reality TV show in Miami on Wednesday, she started wearing the ring after she came back from Rome where Kanye took her to celebrate her birthday. Some are saying it might be a secret engagement. There were speculations that Kanye was going to propose to Kim on her birthday last Sunday. Kim is, however, not officially divorced from  her last husband, Kris Humphies. 

She can't be engaged while still married to someone else, right? Plus the ring is on her pinky finger.
