LOS ANGELES (AP) _ Taylor Swift was crowned artist of the year at the American Music Awards for a second time.

``This is so crazy!'' the country superstar said after beat such contenders as Adele, Lady Gaga and Katy Perry to capture all three awards that she was nominated for at Sunday's ceremony, including artist of the year, the show's highest accolade that she previously claimed in 2009.

``I ended up writing the record by myself, so the fact that you would honor it this way, you have no idea what this means to me,'' said Swift after winning the trophy for favorite country album for ``Speak Now.'' She was also awarded the prize for favorite country female artist.

Nicki Minaj, the pink-loving hip-hop diva, won two awards Sunday. She kicked off the 39th annual fan-favorite ceremony by sporting a pair of speakers on her much-talked about posterior and was later honored as favorite rap/hip-hop artist, besting a group that included mentor Lil Wayne, and won favorite rap/hip-hop album for ``Pink Friday.''

``There's so much love in this room,'' beamed the pink-haired Minaj.

Adele had been the night's leading nominee with four nods, but didn't have much of a presence at the show: She was absent from the ceremony because she is recovering from recent throat surgery. Adele tied Swift with three awards: favorite pop/rock female artist, adult contemporary artist and pop/rock album for ``21.''

Other winners included Maroon 5 as favorite pop-rock band/duo/group, Blake Shelton as favorite country male artist, Lady Antebellum as favorite country band/duo/group, Beyonce as favorite soul/R&B female artist, Rihanna for favorite soul/R&B album for ``Loud'' and Hot Chelle Rae as new artist of the year.

The ceremony inside the Nokia Theatre in an unusually rainy Los Angeles was drenched with 17 musical performances.

Justin Bieber got in the holiday spirit among a forest of neon lights with ``Under the Mistletoe,'' and Kelly Clarkson, wearing a glittery red gown with her hair swept to the side, delivered a swinging rendition of her hit ``Mr. Know It All'' as back-up dancers dressed as 1930s-era photographers snapped the first-ever ``American Idol'' champion.

Jennifer Lopez and Marc Anthony shared custody of rapper Pitbull, who joined the former couple in a pair of separate performances. Lopez performed essentially a live version of a car commercial starring the ``Idol'' judge set to ``Papi'' _ with the car onstage _ before launching into her hit ``On the Floor.'' Pitbull later returned to the stage and joined Anthony for ``Rain Over Me.''

Lopez expressed surprise when she won the favorite Latin music artist award.

``It's been up and down and just exciting and overwhelming and so many things,'' Lopez said of the last year.

Several artists delivered stripped-down performances: The Band Perry crooned an emotional ``If I Die Young,'' a pink-haired Perry accompanied herself on guitar for ``The One That Got Away'' and a platinum-blonde Chris Brown simply sang ``All Back'' before being joined by a troop of helmet-clad back-up dancers for a flashy interpretation of ``Say It With Me.''

There were collaborations, too. Lopez joined a glowing-in-the-dark will.i.am for his new single ``Hard.'' Christina Aguilera dueted with Maroon 5 on their ``Moves Like Jagger,'' and then Maroon 5 lead singer Adam Levine teamed with Gym Class Heroes for their hit ``Stereo Hearts.'' Bieber joined LMFAO in animal-print pants for the show's finale, which ended with everyone on stage _ including David Hasselhoff _ stripping down to smiley-face underwear.
