White got a flash mob greeting for her 93rd birthday

(CNN) The birthday wishes are flowing freely for America's favorite nonagenarian, Betty White, who turned 94 on Sunday.

The actress -- who has worked in show business since the 1940s and may be best known for her role as the sweet and clueless Rose on "The Golden Girls" -- kicked off her birthday week with an appearance on "The Late Late Show with James Corden."

She tucked herself between dashing zookeeper and television personality Jack Hanna and New York Knicks forward Amar'e Stoudemire, according to her Twitter account. (She joined Twitter in 2012 and has 1.26 million followers.)

On her actual birthday, she hung out with the @NFLonFox crowd. "Nothing like spending your birthday with a friend or 8 if they're good looking!" she tweeted.
