Ryan Seacrest sparked dating rumors after several media outlets posted photos of his alleged girlfriend Renee Hall wearing a large diamond ring on her ring finger. However, TMZ reported that the news was false as paparazzi mistook another woman for Hall.

The "American Idol" host was spotted at London's Heathrow Airport Sunday along with a group of longtime friends. Hall's look-alike was pictured at the airport along with Seacrest, giving rise to speculation that the 40-year-old may have popped the question to his model girlfriend, whom he has been reportedly dating for nearly nine months.

The woman was later identified as Sarah Much, who is engaged to American real estate businessman Kurt Rappaport. Seacrest spent the Thanksgiving weekend with Much and Rappaport in Europe.

Seacrest sparked dating rumors with Hall in March after the model attended the former's birthday bash in Napa Valley, California. In June, reports surfaced that Seacrest was dating Miss Teen USA 2007 Hilary Cruz.

The “Keeping Up With the Kardashians” executive producer's last confirmed relationship was with model and fitness enthusiast Shayna Taylor, with whom he split in late 2014.
