Music's favorite couple was feeling Hella Good last weekend! After the Academy of Country Music Awards on April 15, Gwen Stefani took the stage at an after party to bust out some of the old music from her No Doubt days, and her handsome boyfriend Blake Shelton joined her on stage! Watch the video above to see him groove to "Hella Good," plus a little adorable PDA!

Perhaps Gwen decided to play some of her old songs at the after party show to get her ready for her brand-spankin'-new Vegas residency, which she announced in April and begins in June. Unfortunately, that means that she won't be working on The Voice anymore, but Blake seems plenty supportive of the move anyway. While it's unclear whether Gwen will be moving to Vegas with her three sons during the residency, the family has gotten pretty good at splitting their time between different homes. While Gwen and Blake live together in Los Angeles, Blake also has a ranch in Oklahoma that the whole squad often visits. Now they'll just have to throw Vegas into the mix, too!

It's a great thing that Blake and Gwen both love music, performing, and each other, because a source tells Life & Style exclusively that they're planning to collaborate for the rest of their lives. "Her dream is to marry Blake and have his child," said the friend. The couple already has a wedding planned in Mexico for sometime this summer, and we can only imagine how great the music at the reception will be. "I think about [marriage] all the time," Gwen recently admitted to Ellen DeGeneres. Luckily she doesn't have to imagine much longer!
