Although fans were excited to see Cee-Lo Green and Goodie Mob back together, the true star of the set was Jean Sok, a one-legged dancer from Cirque du Soleil's Michael Jackson The Immortal World Tour. Dressed as a soldier, Sok gave a truly powerful performance and left a lasting impression on viewers.
Clad in white Adidas tracksuits, the hip-hop foursome (Cee-Lo Green, Khujo, T-Mo, and Big Gipp) then surprised the audience by launching into the Beastie Boys classic, "(You Gotta) Fight for Your Right (to Party!)," as a tribute to Adam "MCA" Yauch, who lost his battle with cancer earlier this month.
In other Billboard Music Awards news, Katy Perry picked up the Spolight Award for matching Michael Jackson's record of five No. 1 singles on the Billboard charts off a single album.
Teenage Dream spun off the No. 1 Hot 100 hits "California Gurls" (featuring Snoop Dogg), "Teenage Dream," "E.T." (featuring Kanye West), "Firework" and "Last Friday Night (T.G.I.F.)." The singer nabbed yet another No. 1 this year, with "Part of Me," the first single off the special edition album Teenage Dream: The Complete Confection.
Perry, who brought her 91-year-old grandmother to the awards show, debuted her new single, "Wide Awake," live on the BBMA stage. The track was written for her upcoming 3-D film Katy Perry: Part of Me.
Meanwhile, Taylor Swift was honored as Billboard's Woman of the Year, with actress Zooey Deschanel presenting the country crooner's award for her chart-topping records, sold out concerts and for being, well, adorkable. Swift was actually named Billboard's Woman of the Year in October 2011, but why not celebrate it twice?
Billboard also honored the life of music legend Whitney Houston, who passed away in February 2012. Musicians John Legend and Jordin Sparks were on hand to perform a medley of Houston's greatest hits. Sparks, who starred oposite of Houston in her last film "Sparkle", performed Houston's seminal single, "I Will Always Love You." Houston's daughter, Bobbi Kristina, accepted the Billboard Millennium Award on her mother's behalf.
"I just really want to say thank you to everyone who supported us through it all," she said. "Not just when it was good, but when it was bad too ... Thank you so much for showing that much love, because she deserved it."
Hosts Ty Burrell and Julie Bowen, the stars of ABC's "Modern Family", also paused for a moment of silence for the recent passing of Bee Gee Robin Gibb.
Singer Natasha Bedingfield paid tribute to disco legend, Donna Summer, who also lost her battle with cancer just last week.
On a lighter note, Alicia Keys honored Stevie Wonder with the Billboard Icon Award. The duo performed a medley of Wonder's hits, "Higher Ground" and "Overjoyed." But before getting off the stage, the pair had one more surprise in store. With a little encouragement from Wonder, who recently celebrated his 62nd birthday and had one wish for the soulful songstress, Keys belted out the chorus of Jay-Z's "Empire State of Mind."
