The British boy band are performing at the music channel's prestigious award ceremony in Los Angeles later, and can't wait to meet some of their idols at the show.
Niall Horan told MTV: ''We're excited to see Green Day because growing up Green Day were like one of the big bands around of our generation. It'd be exciting to meet them.''
Speaking about loudmouth Pink, he added: ''I think it'd be nice to meet her because she kind of does her own thing.
''It's going to be nerve-racking, but we're trying to do our best.''
He said: ''Frank Ocean's performing. I'm excited to see that.''
When asked who he'd most like to meet, the cheeky star replied: ''All the single ladies? I think it'd be nice to see Katy Perry again. We've seen her a few times now.''
The awards will be broadcast live on MTV in the US at 20:00 Pacific Time.
