It was rumored that Ryan Seacrest had popped the question to onetime girlfriend Renee Hall after he was photographed at the airport with her doppleganger, who was wearing a huge rock on her ring finger, but apparently it was all a big misunderstanding! The woman was actually his pal Kurt Rappaport's fiancee Sarah Much, and he was traveling to London with the couple.

"I'm not engaged! That's not true," the radio host told our videographer after we asked about the reports.

Last we checked, the American Idol host was in a relationship with beauty queen Hillary Cruz, but we haven't seen them together for a while. Perhaps Hollywood's busiest man is back on the market?
