Paris Hilton Spending Alot of Time Alone in London Without Benji Madden

Paris Hilton is seen here leaving and arriving back at her London hotel after a night out at the Kingly nightclub in soho, London. Curiously enough, though, is that Benji is no where to be seen. Perhaps they are spending some time apart?

And later in the evening when she returns back to her hotel - again - no Benji in sight. In February of this year when Benji split from fiancee Sophie Monk, Paris and Benji were suddenly inseparable. Now Paris Hilton and Benji Madden have not been seen together in weeks. Are there problems in Paris' paradise?
