John Cena may have already given Nikki Bella a gorgeous engagement ring [1], but now he's taking things back to high school. While appearing on The Ellen DeGeneres Show [2] on Friday, the 40-year-old actor revealed to the host that he never went to his own prom [3] because he went to a co-ed boarding school and chose to spend the night working instead. So, in true Ellen fashion, she gave John the big night he never had and surprised him with awkward photos, slow dances, and of course, his beautiful fiancée Nikki Bella [4]. Watch the adorable clip above, and then, check out the photos of John and Nikki's over-the-top romance [5].
