John Mayer may have been the main act at the Nokia Theatre on Dec. 8, but Fergie and Josh Duhamel only had eyes for each other. The superstar singer and her 35-year-old Las Vegas beau made it a "date night" at the concert and had the time of their lives.
“They were dancing, hugging, holding hands and just having a sensational time,” an eyewitness tells OK! “They’re so comfortable with each other they didn’t even care when fans recognized them and asked for photos and autographs."
Fergie, 32, and Josh are famous for their karaoke singing and even have their own machine at home.
“Josh may not be the professional singer Fergie is,” the eyewitness says, “but they sounded pretty fantastic together singing along to John Mayer.”
