But the love of her life, Shelton had a special request as he asked Stefani to sing "Hella Good" which made the crowd very much excited.
His girlfriend Gwen Stefani joined him onstage.
In an interview with Marie Clare a year ago, Stefani called Shelton her "best friend", adding, "For a long time, I could not understand why I'd had so much heartache in my life". As the Inquisitr reported last week, she teased a possible wedding with the singer.
The couple also hit the stage together at Shelton's "BS and Friends" after party show at the Mandalay Bay House of Blues, where Stefani came out for a surprise set. The song, which reflects a lot of the singer's personal upbringing, left the audience connecting deeply to the message and they gave Shelton a standing ovation after he finished.More news: Manchester City to avoid ban from CAS

"It just keeps getting better and cuter and more country", she said.
Her chat with DeGeneres started off with a reference to Shelton's title as PEOPLE's Sexiest Man Alive, with Stefani adding that he only "got sexier" after that.
"It's interesting because I don't think any of those things like beauty or sexy or whatever way you want to describe humans is necessarily a physical thing that people are attracted to", Gwen Stefani continued. But it doesn't sound like he thinks about it exactly all the time. "The more time that goes by, I guess, the closer you would be getting to that", he said.
