'Golden Girl' Betty White turns 90 years young today, and she celebrated last night with a televised bash that included a message from Pres. Obama and a marriage proposal.

In pre-taped segment Barack Obama expressed disbelief that White could be turning 90, and demanded she produce her long-form birth certificate. The 'Hot in Cleveland' star was then roasted by TV luminaries such as Amy Poehler, Tina Fey and Carol Burnett. She also planted a kiss on the lips of 'Chuck' star Zachary Levi after he got down on his knees and proposed marriage to the soon-to-be nonagenarian.

Despite her age, White shows no signs of slowing down, and will be hosting the the hidden camera show 'Off Their Rockers' this year, in addition to her duties on 'Hot in Cleveland.' Check out highlights from 'A Tribute to America’s Golden Girl' below.
