The Twilight threesome checked into the five-star Crillon hotel, where they all have separate suites that cost a cool $3,233 per night.
Yes, Robsten lovers, you read that right. Separate suites. But that doesn't rule out late-night visits...right?
"They could have sneaked into each other's rooms," a hotel source tells E! News. "We wouldn't know a detail like that."
Sleeping arrangements aside, the cast headed to dinner at a restaurant of Rob's choosing...
The group dined at the fancy Costes hotel restaurant, where they shared smoked salmon, foie gras and spring rolls.
"Rob has been there before and wanted to show it to Kristen and Taylor," says a source.
While K.Stew and Tay sipped water, R.Pattz downed two Bellinis—swanky, but we always figured him as more a beer guy.
The costars called it an early night and were back at the Crillon by 11 p.m. "They all seemed very jet-lagged," a source says.
Not too tired to sign autographs for some lucky fans, though.
"They all signed pictures for the fans who had waited in the cold," one fan tells E! News. "We asked Rob if he was enjoying Paris and he said; 'Of course! It's always been one of my favorite cities!'"
Hope he makes the most of his short stay...the group heads to London tomorrow for the next leg of their press tour.
While you're waiting for New Moon, you can catch the cast in action as they promote the movie on their world tour!
