Are they really over? It might be true. Kristen Stewart and Robert Pattinson haven't been spotted together in almost 3 weeks. Sources close to the couple are saying they got in a huge fight during the Cannes Film Festival and they've been taking a break since then. "At Rob's Cosmopolis party, she lost her temper... She says he was flirting with other women, but he wasn't at all. She was in the lobby in tears." Oh no, poor Kristen! The couple had such a big fight that they even stayed in separate hotels, Rob stayed at the Hotel du Cap-Eden-Roc and Kristen stayed at the Hotel Martinez. With the Twilight saga soon ending, it seems only natural that KStew and RPatz would end too.
