By now, the world knows Lady Gaga is a good egg.
How good? We'll let the photos of the gi-normous cake she got for her performance partner, Tony Bennett.
Bennett turned 89 Monday and appeared quite touched as Gaga had the cake wheeled out onto the Kennedy Center stage Saturday night.
Duff Goldman 's Charm City Cakes, baked the imposing tower of love.
Gaga, 29, serenaded her friend with Duke Ellington's "I'm Beginning To See The Light."
Then she led the audience in a rousing round of "Happy Birthday."
