So far, 2010 has been a whirlwind year for Betty White -- and it's only June. The 'Saturday Night Live' episode she hosted garnered landmark ratings, and she's appeared on seemingly every daytime and late-night talk show. Now she's starring in 'Hot in Cleveland' on TV Land.

This has Jon Stewart of 'The Daily Show' (weeknights, 11PM ET on COM) concerned for the 88-year-old.

"Your career is booming; it's on fire. I see people get this type of success, especially actresses, starlets, and they can't handle it," said Stewart. "I'm worried about you having a Britney phase."

"No I'm fine, I'm absolutely fine," White responds. But the face of the comic genius says otherwise.
