BLAME IT ON THE AL-CO-HOL! MARIAH GETS ON STAGE A LITTLE TIPSY!

Mariah Carey was busted for BUI in Palm Springs last night -- babbling under the influence -- as she made a drunken mess out of herself while trying to give an acceptance speech at an awards show.
At last night's Palm Springs Film Festival, Mimi took home the prize for Best Supporting Actress for her role in "Precious" -- but when she attempted to talk, it was pretty clear Mariah was the one who needed the support.
