Who says age matters? Betty White had a fabulous 90th birthday bash, in which she may or may not have made out with 31-year-old Chuck star Zachary Levi.

Soooooo, I may have just made out with Betty White. This is not a joke. #bucketlist tweeted the actor Sunday night.

The star-studded festivities were for an NBC TV special, Betty White's 90th Birthday: A Tribute to America's Golden Girl. A-list guests like Tina Fey, Morgan Freeman, Ellen DeGeneres and Joel McHale gushed about the beloved comedian at the Millennium Bilmore Hotel party on Sunday.

When you work with Betty, you feel like you're a kid who's won one of those radio contests to get to go meet your favorite person on Earth and just be in their presence, Jennifer Love Hewitt told People about White. I just sit there all day and stare at her. Sometimes I'm like, she must really think I'm weird, because I'm still looking at her. She's the best.

But come Jan. 17 - White's actual birthday - the indomitable Hot in Cleveland star said she's looking forward to quieter plans.

I'm going to sit back home with my golden retriever Pontiac, she told reporters before the Sunday taping. 'Usually I'll try to play catch-up with all the things I never will catch up on. I may just do crossword puzzles and indulge myself and have a wonderful time with my dog.

The NBC tribute is slated to air on Jan. 16, according to Hollywood.com.
