Harry Potter and the Deathly Hallows: Part 2 -- the last installment of the hit movie franchise about the British boy wizard -- won four awards, including best movie and favorite ensemble cast.
The Harry Potter stars did not make the trip from Britain to the awards show in Los Angeles so none of their wins were announced on the two-hour televised ceremony.
Perry won five trophies, including best female music artist, favorite song for "E.T." and favorite tour headliner. But the perky "Firework" pop star pulled out of last night's live TV ceremony at short notice, following her split with British comedian Russell Brand two weeks ago after 14 months of marriage.
Female romp Bridesmaids won best comedy movie and Johnny Depp picked up the best actor award.
Emma Stone, 23, took the trophies for both movie actress and favorite comedy actress for her roles in civil rights era film The Help and Crazy, Stupid, Love.
"I moved to LA eight years ago this week with my mom and it is so insane to be standing up here right now," Stone told the audience.
Former Disney Channel star Demi Lovato, 19, was voted favorite pop artist following her return to showbusiness after an emotional breakdown in late 2010, beating the likes of Lady Gaga and Beyonce. She also performed (see video below).
Television honors included Glee star Lea Michele and Neil Patrick Harris for How I Met Your Mother, which also won favorite TV comedy show.
