Billboard Music Awards: Beyonce Accepts Millennium Award

Plus, watch the singer perform her new single, "Run the World (Girls)," at the Las Vegas show.

Beyonce's reign is stronger than ever -- that was clear at Sunday night's Billboard Music Awards on ABC, where the star received the Billboard Millennium Award and performed her new single, "Run the World (Girls)," for the first time on network television. 

Several of Beyonce's close relatives, famous friends and collaborators -- including First Lady Michelle Obama, Lady Gaga, The-Dream, U2's Bono, Babyface, Stevie Wonder, sister Solange and her son Daniel "Juelz" Smith, Barbra Streisand, Matthew Knowles and Tina Knowles -- took part in the Billboard Millennium Award presentation with pre-recorded personal messages about the singer's accomplishments and impact. Lady Gaga, who collaborated with Beyonce on remixes of their singles "Telephone" and "Videophone," summed it up best: "You represent the dream," she said.

The honoree herself then took the stage in a barely there silver number to perform "Run the World (Girls)," the lead single from her fourth studio album, 4, for the first time ever. Virtual duplicates of Queen B rocked behind her until an impressive 100 back-up dancers emerged to rock collectively to the girl-power anthem. 

After the show-stopping performance, Tina Knowles and Juelz presented Beyonce with the Billboard Millennium Award, as the singer breathlessly thanked her parents, Destiny Child's Kelly Rowland, Michelle Williams and even former members of the group, LaToya Jackson and LaTavia Roberson.

Beyonce ended her speech by shouting out her husband --  "I love me some Jay-Z," she said, as the rap star smiled and nodded and a collective "aw" could be heard in Las Vegas' MGM Grand Arena and on social networks. 

The 2011 Billboard Music Awards are being broadcast on ABC from Las Vegas with performances by Nicki Minaj, Lady Antebellum, Cee Lo Green, Taio Cruz, Far East Movement and Ke$ha.
