Christina Aguilera and Nickelback gave a private concert to Microsoft employees in Denver on Friday, according to the talk on Twitter.
The concert took place Friday in Denver, where the company held its annual Microsoft Global Experience or MGX conference for its sales people. The chatter on Twitter says it was at the Red Rocks concert venue.
Earlier in the week, rumors circulated that Lady Gaga and the Red Hot Chili Peppers were going to play.
Microsoft usually throws a private concert on the final day of MGX. Last year the Black Eyed Peas played.
The tweets are all unconfirmed. Microsoft declined to comment on MGX.
Visit Denver, the tourism bureau for the city, said it had expected 12,500 people at the Colorado Convention Center for the Microsoft event last week from Tuesday to Friday.

Here is a video that surface on Youtube from user WeLoveAguilera. The quality is poor, but around the 2:49 mark you can hear Aguilera say, “Micros-sooooooft.”
