Well-loved actress and comedian Betty White is going to be 100 soon — and she's letting the world know it.

On January 17, 2022, she says, she'll be "100 years young."

"I'm going BIG for my birthday," she writes to her fans on Twitter, "right to the BIG SCREEN!"

In the tweet sent out last night from her account on Twitter, White — who has worked continuously in Hollywood since her 20s — told fans in words and video about an upcoming one-day-only film event that will help celebrate her 100th birthday. (And yes, tickets are required.)

She's called herself "a lucky old broad" who's been "blessed with good health."

The native of Oak Park, Ill., has enjoyed a highly successful career in radio, TV, and film spanning more than 75 years.
