Beyonce, Taylor Swift, Justin Bieber Shine at Billboard Awards

The stars were out at last night's 2011 Billboard Music Awards, and some of music's most recognizable faces won big. Hosted by The Hangover's Ken Jeong, the three-hour show certainly did not disappoint, filled with mega-watt star power and amazing performances.

Country sweetie Taylor Swift took home two trophies, one for 200 Album Artist of the Year for her Speak Now album, and another for Country Artist of the Year. "I'm just havin' the best time doin' this," she said while accepting.

Bieber Fever took over the MGM Grand in Las Vegas, as 17-year-old Justin Bieber was a triple winner for Digital Artist of the Year, Top New Artist and Fan Favorite. And we can't forget about the fourth trophy that he had with him all night as well -- his beautiful girlfriend Selena Gomez!

But it was Beyonce who garnered most of the night's loves, as the singer was awarded with the Billboard Millennium Award, for her music and for her foundation's humanitarian work. Tons of huge names, from First Lady Michelle Obama to Barbara Streisand to Stevie Wonder, paid tribute to Beyonce as an artist and a do-gooder. After putting on a rockin' performance of her new song, "Run the World (Girls)," B accepted the trophy from her mom, Tina Knowles.

Overwhelmed by the moment, Beyonce thanked her family, her former Destiny's Child sisters Michelle Williams and Kelly Rowland, before shyly shouting out to her "best friend," husband Jay-Z.
