Rihanna and Chris Brown Still On!

Rihanna and Chris Brown are doing a really bad job of pretending they're not a couple.

First they were spotted getting hot and heavy in Jamaica, a week later they were sucking face in Paris, and were just spotted leaving a London hotel together early this morning.

Spies who spotted the couple said they left Maya nightclub around 3AM before heading to their hotel room. Vacationing in London together? Now that doesn't sound "single" to us!
