Singing, dancing, a plethora of aging jokes and a lineup of celebrity guests pepper NBC's televised birthday bash for "Golden Girls" and "Hot in Cleveland" star Betty White Monday.
But the Emmy winner also gets a surprise marriage proposal -- and responds with a surprise smooch -- from "Chuck" star Zachary Levi.
"Betty White's 90th Birthday: A Tribute to America's Golden Girl" (8 p.m.) includes appearances and White tributes from Mary Tyler Moore, Tina Fey, Carol Burnett, Amy Poehler, Ellen DeGeneres, Carl Reiner, Joel McHale, Hugh Jackman and Ray Romano, among others, and will be followed by a preview episode of her upcoming hidden-camera prank series "Betty White's Off Their Rockers."
