The honours keep pouring in for 91-year-old actress Betty White, who has been named America’s most appealing celebrity, according to a market research firm.

White, who stars on the sit-com Hot in Cleveland,” narrowly topped Oscar-winners Sandra Bullock and Tom Hanks, and other celebrities such as singer Adele and Dame Maggie Smith of Downton Abbey fame on E-Poll Market Research’s annual “appeal” list for 2012.

It was White’s third time at the top of the list, which was released yesterday.

Others making the list’s top 10 included Morgan Freeman, Carol Burnett, actress and recording star Cote de Pablo, “NCIS” TV star Pauley Perrette and Olympian Gabby Douglas.

Robin Williams and Clint Eastwood dropped out of the top 10.

White has collected Screen Actors Guild awards for her current show, hosted Saturday Night Live in 2010 and was recently rated as the most popular and trusted celebrity in other national polls.

The ratings also looked at which celebrities saw the biggest gains in their appeal factor last year, with Olympic athletes Misty May Treanor, Kerri Walsh, Aly Raisman and Michael Phelps all making the top 10, likely due to exposure from the 2012 Summer Games in London.
