Gwen Stefani [1] and Blake Shelton turned the Billboard Music Awards into their very own date night [2] on Sunday. The couple took the stage at the T-Mobile Arena in Las Vegas to perform their duet, "Go Ahead and Break My Heart," [3] and in addition to sharing cute moments together [4] on stage, they also shared intense and consistent eye contact. The two literally didn't break or look away for anything, something that was also noticeable during their performance on The Voice [5] earlier this month. While some may find the staredowns sweet, others might just squirm while watching them unfold. Either way, these two are definitely in love [6]!
