Gwen Stefani and Blake Shelton turned the Billboard Music Awards into their very own date night 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," and in addition to sharing cute moments together 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 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!
