X17 photographers were the ONLY ones to catch Kristen Stewart and Rob Pattinson after a steamy night together, post-MTV Movie Awards!

The Twilight co-stars are DEFINITELY off-screen sweethearts as well, as these exclusive pictures confirm. After the awards show, Rob and Kristen headed to Cecconi's for a bite to eat, and the duo left the trendy eatery around 11pm, and they were followed by a police escort to The Charlie Hotel in West Hollywood (Charlie Chaplin's old house). The lovebirds booked themselves a private chateau, and we didn't see them again until noon, when they emerged from their bungalow, looking like they'd both just rolled out of bed!

Our X17 photographer on the scene tells us exclusively:

"Rob was preoccupied with getting all of his stuff in the car and Kristen was hiding behind her sunglasses, looking a little tired, but waiting to say goodbye. Right before Rob got in the SUV, the couple stood together behind the car door and I'm pretty sure there was a brief kiss!"

Rob was whisked away to LAX in a dark SUV, and Kristen retreated to the bungalow, presumably to catch up on sleep.

Rob and Kristen def seem to be teasing their fans with this are-they-or-aren't-they relationship, but X17online can announce to Twilight fanpires - this relationship is for real!
