The German model hooked up with PSY for a masterclass in Gangnam Style before presenting the bash live from Frankfurt's Festhalle, even wearing the South Korean singer's iconic blue jacket, sunglasses and bow-tie.
Klum took to Twitter to post a picture of their meeting, writing: "Now I know how to dance Gangnam Style!"
Heidi has made no secret of her desire to perfect PSY's famous horse-riding dance, previously telling The Sun: "I’ll have to perform it. I have four small children and they are obsessed with the song. We do Gangnam dance parties at the house.”
Former Baywatch actor David Hasselhoff also got a piece of the Gangnam Style action, tweeting a snap of himself and PSY, along with the caption: "Getting lessons from the master backstage @psy_oppa #MTVEMA #gangnamstyle."
As well as dressing like PSY, Klum is expected to stun the EMA crowds tonight with a variety of costumes, revealing to BANG Showbiz: "I have six different outfits from Versace that I love very much and I think for an event like the MTV awards I usually have a little bit more fun, I can be a little bit more sexy, a little more rock 'n' roll.
"So they have got me beautiful outfits, great shoes and great jewellery, but it depends how much time I have to change in between (hosting) because it's all live."
