The Oscars were certainly entertaining last night with Hugh Jackman singing and dancing his heart out. Many of our faves joined in the fun, too: Anne Hathaway sang a duet during the opening number; and co-starring couples Zanessa and Amanda Seyfried and Dominic Cooper reprised some Mamma Mia! and HSM songs in a big ol' medley, while Beyoncé led them all in a fabulous rendition of "At Last." (The movie musical is certainly back and in full effect!) Overall, it was a fun awards show. In case you weren't watching, the winners are... Kate Winslet for Best Actress, Sean Penn for Best Actor, Penelope Cruz for Best Supporting Actress, and Heath Ledger for Best Supporting Actor. The entire (adorable!) cast of Slumdog Millionaire graced the stage to pick up their award for best picture of the year. Were you happy with the results? Tell us below!
