Chris Brown completed his rehabilitation at last night’s BET Awards at the Shrine Auditorium in L.A. by earning four awards, including Best Male R&B Artist, Video of the Year, Best Collaboration and the Viewer’s Choice Award, though the latter was mistakenly awarded to his ex, Rihanna, then Drake, before the error was finally rectified.

The show was hosted by comic Kevin Hart, who kept the crowd laughing as part of his “Real Husbands of Hollywood” opening sketch with Bobby Brown, Jermaine Dupri, Anthony Anderson, Nelly and Nick Cannon.

But it was the comebacking Brown who stole the show with his medley of "She Ain't You," "Look at Me Now" and "Paper Scissor Rock,” as well as a performance with Busta Rhymes and Kanye West protege Big Sean.

The evening’s big mix-up occurred when a fan who was selected to present the Viewer’s Choice Award, first announced Brown’s name as the winner, then changed to Rihanna, then gave it to Drake, who accepted the honor before it was revealed Brown was the actual choice.

Brown and Rihanna, of course, were involved in a notorious fight before the Grammys two years ago which left the diva battered and bruised. Rihanna was named Best Female R&B Artist.

In another TiVo moment, Justin Bieber propositioned Nicki Minaj on stage: "I'm all grown up now. I turn 18 next year so...what's up?"

Legendary diva Patti LaBelle was the recipient of the Lifetime Achievement Award, with a tribute featuring Gladys Knight and Cee Lo Green, who took he stage in a throwback LaBelle costume performing "Somebody Loves You Baby," while Marsha Ambrosius jazzed up the room with her spot on rendition of "If Only You Knew," before the great Shirley Caesar took the crowd—and the honoree—to tears singing "You Are My Friend." Patti herself then brought the house down, performing two of her greatest hits, "Love, Need and Want You" and "Lady Marmalade."

Steve Harvey was honored with the Humanitarian Award. The cast of the Five Heartbeats movie reunited with R&B crooners After 7 to perform the hit, "Nights Like This," for the 20-year anniversary of the film. Kerry Washington graced the stage for BET's “Shine a Light” moment to honor individuals who make the world a better place for young people.

Celebrating the 10-year Anniversary of her recently re-released debut album, Songs In A Minor, Alicia Keys graced the BET AWARDS '11 stage for a medley of her hits with Bruno Mars and Rick Ross as well as for the world premiere of her latest song, "Typewriter."

Additional highlights of the 14 performances included: Trey Songz’ sexy, shirt-ripping rendition of "Making Love Faces" and "Unusual," later joined by Kelly Rowland to perform her smash hit, "Motivation”; Donnie McClurkin, Deitrick Haddon and Mary Mary uplifted the audience with their rendition of the gospel hit, "Thank You Lord," in tribute to the late Walter Hawkins; Mary J. Blige, Anita Baker, DJ Khaled and Jadakiss kicked off the show with a monumental mix of hits "All Night Long," "Joy," "Happy," Dreams," "Real Love," "Rapture" and "Over Til It's Over"; Jill Scott performed a soulful rendition of "Rolling Hills" with actor and DJ Idris Elba; DJ Khaled, Rick Ross, Drake and Lil' Wayne amped the crowd with "I'm the One"; and Beyonce closed the show singing "Best Thing I Never Had" and "End of Time" via live telecast from Britain's Glastonbury Festival.

This year's In Memoriam tribute celebrated the lives of Cali Swag District member M-Bone, Clarence Clemons, Teena Marie, Gil Scott Heron and Nate Dogg with performances and appearances by Doug E. Fresh and Cali Swag District, Queen Latifah, Ledisi, Scott Mayo, Snoop Dogg and Warren G.

In continuing the good that BET's S.O.S.: Saving Ourselves initiative has made over the years, the BET AWARDS '11 contained a special moment to show support for the victims of the tornadoes in the Southeast through a special message from Rev. Al Sharpton.
