Despite her red-hot romance with MTV reality star Doug Reinhardt, socialite heiress Paris Hilton is still in close contact with former boyfriend Stavros Niarchos.

The 28-year-old Paris has been calling the Greek shipping heir at least three times a week unbeknownest to Doug, according to recent whispers.

“Paris and Stavros are still good friends and speak on the phone quite a bit. Doug knows they are close, but not how often they speak.”
