Talk about relationship goals! On Wednesday, Gwen Stefani took to Instagram and uploaded a cute couples' selfie [2] featuring boyfriend Blake Shelton, Adam Levine, and his wife, Behati Prinsloo. Along with the photo, which was most likely taken on the set of The Voice, Gwen simply wrote, "@behatiprinsloo @adamlevine @blakeshelton Gx 😘.." Earlier this week, Gwen and Blake took the Voice stage together and performed their duet, "Go Ahead and Break My Heart," [3] for the very first time. Meanwhile, Behati and Adam have been busy gearing up for the arrival of their baby girl [4], and last week, the Maroon 5 frontman grabbed headlines when he posted a hilarious shot of him and his wife [5] showing off their matching bellies. See Gwen's post above now, and then check out her cutest photos with Blake [6].
