The pair were reportedly seen checking into an LA hotel together after the MTV Movie Awards on Monday.

They dined at Cecconi's until 11pm when they were accompanied by a police escort to The Charlie Hotel in West Hollywood.

According to celebrity website Bang Showbiz, the couple didn't leave their private bungalow until noon the following day.

Stewart has previously denied she was dating Pattinson.

"It's just totally false. Robert and I are good friends. We went through a lot together, so we feel very close." -- AP
