While it is believed that everything went off without a hitch, there may have been a little issue with the lighting during the some of the stage performances.

During Rihanna's performance with West and McCartney, the singer appeared to look a little orange.

The trio took the stage to perform Rih's new single FourFiveSeconds, and while she gave the performance of a lifetime, which can be seen in the video blow, her skin complexion looked orange. Did Rih Rih have a make-up mix up backstage, or was it simply a matter of the lighting being slightly off?

Gaga was another one whose skin looked slightly off. The singer took the stage with Tony Bennett to perform their single Cheek to Cheek. The singer was another victim of poor lighting. During her performance, her skin also appeared to look another color.

Clearly the lighting issue was only a minimal issue. Both Rih and Gaga took home awards last night. Rihanna took home an award for Best Rap/ Sung Collaboration for her partnership with Eminem for The Monster. Gaga took home another trophy as well. The singer won the Grammy for Best Traditional Pop Vocal Album Cheek to Cheek with Bennett.

As of now, there's been no word on this issue, but be sure to check in for more updates about their performances and for more Grammy Awards news and updates.
