Anyone who's spent five minutes watching the 'Ellen DeGeneres Show' knows how fond the TV host is of dancing, so of course she's dancing in the streets to celebrate her upcoming gig as host of March's Academy Awards.

In a brand-new Oscars trailer directed by Paul Feig ('Bridesmaids'), Ellen and some 250 backup dancers don their suits and ties -- make that tuxedos and bow ties -- and shake their stuff to the poppy song 'The Walker' by Fitz & the Tantrums. The number, which was filmed on the Warner Bros. studio lot, was choreographed by 'So You Think You Can Dance' star Stephen "tWitch" Boss.

"Paul Feig has a reputation of being hilarious and nice and smart," Ellen dishes in a behind-the-scenes video. "I thought this is a great idea and I loved it. And I want to be in 'Bridesmaids 2,' so 2+2: great Oscars promo, 'Bridesmaids 2,' cha-ching."
