Page Six says today that the on-again / off-again relationship between Josh Hartnett and Scarlett Johansson may be back on again. Hartnett and Scarlett were seen together Friday night at the TriBeCa restaurant Cercle Rouge. A source says:

“They had a meal and got progressively cozier as the night went on. Then they started to make out in full view of the restaurant at their table and didn’t really care who saw.”

Hopefully they are back together. He seems a little possessive though I dunno. But they do work a million miles away from each other and only see one another once and awhile. So you can see why celebrity relationships are so hard. The money is great but your social life sucks because it can be demanding!
