Paris Hilton’s on-again, off-again BF shipping heir Stavros Niarchos was in Europe when Paris Hilton was thrown back into the slammer. In Touch Weekly reports the man-beauty was emotional and kissing the glass when he saw the hotel heiress behind bars for the first time on Sunday.

“He burst into tears as he was led into the visiting area,” Stavros’ friend said. “He found it hard to look at Paris because she seemed so frail and gaunt.”
