( CNN ) -- Michael Jackson 's `` live '' performance at the 2014 Billboard Music Awards brought a mixed reaction Sunday night . `` Uncomfortable , odd and eerily interesting , '' is how public relations agent Simone Smalls summed it up in a tweet . `` Not quite sure what to feel . # MissingMJ '' Uncomfortable because Jackson died nearly five years ago while preparing for a comeback tour . His remains are resting in a crypt in a Forest Lawn mausoleum . But technology tricked viewers -- and the celebrity audience in the MGM Grand Garden Arena in Las Vegas -- into suspending disbelief for a few minutes to watch the pop icon onstage dancing and singing his `` new '' song `` Slave to the Rhythm . '' Ludacris , the rapper-actor who hosted the show , actually introduced it as `` Live from the MGM Grand , Michael Jackson . '' `` He 's baaaccck ! '' Mark Cuban , the owner of an NBA team and TV channel , tweeted about Jackson 's `` hologram . '' Cuban added an Instagram video . The dance moves were not really Michael Jackson 's but apparently those of a stand-in performer who recreated his steps for a computer that then laid on an image intended to replicate Jackson . But where was the swagger -- like Charlie Chaplin -- that characterized Jackson 's cool walk ? `` I wish it would have actually looked like him , '' one fan said . It was eerily interesting because the illusion was effective if you did n't watch too closely or were n't obsessively familiar with Jackson 's dancing , walking and appearance . `` I enjoyed it . Could have had better face but overall it was great . Will have it on repeat , '' a diehard Jackson fan tweeted . # kendallyouhadonejob . Imagine Ed Sullivan confusing the Beatles with the Beach Boys when he introduced the British group 's first live U.S. television performance 50 years ago . That 's the modern equivalent of what Kendall Jenner did at the Billboard Awards . The reality TV personality , model and Kardashian half-sister caught herself halfway through introducing the Australian boy band 5 Seconds of Summer as One Direction . `` Now , we welcome One ... Guys , I 'm the worst reader ! '' Jenner said as she dived below the camera shot . She quickly tossed to a video of the group -- which included a short clip comparing their arrival in the United States to the Beatles ' 1964 invasion . Jenner never fully recovered . The television audience only heard her say `` of Summer '' when she resumed the intro after the video . Twitter had a blast with the 18-year-old 's flub . Two hashtags soon trended : # kendallyouhadonejob and # KendalljennerItsFIVE . But many -- including Jenner herself -- agreed on one thing . Kendall Jenner looked great on the red carpet . Lorde 's message . Lorde wants you to know she 's no longer the young 15-year-old who recorded `` Royals , '' a song that spent much of last summer at the top of the charts and was honored Sunday as the `` top rock song . '' `` What I wanted to say was that I am 17 and a half now , '' Lorde said as she accepted Billboard 's top new artist award . When laughter erupted with that remark , she stopped to say `` that was n't a joke . '' Lorde 's said she 's had `` the opportunity to grow and learn as a new artist '' in the last year `` in the spotlight . '' She later performed `` Tennis Court , '' another song from her younger years . The irony not lost on the Billboard audience is that many people are surprised to learn that the mature talking-acting-looking New Zealander is actually a teenager . # Lordeis17 became a trending topic on Twitter worldwide .

Michael Jackson fan : `` Not quite sure what to feel '' about `` hologram '' performance . Fans complain it was n't as good as MJ , but what else is ? It's a new technology and I think they did the best with it. Lorde says she 's not the 15-year-old she was when she recorded `` Royals ''
