Beyonce, prepare to be bowled over. A highlight at this weekend's Billboard Music Awards in Las Vegas will undoubtedly be the tribute to honor the pop star with the Millennium Award. And the stage will be overflowing with famous friends saluting her talent.

Access Hollywood is reporting that none other than First Lady Michelle Obama will step into the spotlight take part in the tribute. Beyonce serenaded President Obama and his wife with 'At Last,' as they danced at an inauguration ball in early 2009.

Insiders say other luminaries eager to honor Beyonce include Lady Gaga (her collaborator on the hit single 'Telephone'), Bono, Stevie Wonder and Barbra Streisand.
