I think they're really true - can't see a magazine like ok buying the photos of a faux wedding - and also if it was a hoax, it was a very elaborate one, with a designer brides dress, 4 or 5 bridemaid dresses, a wedding cake etc
Heat magazine published copies of documents that they said proved it was a fake wedding about 3 weeks ago, but I wasn't convinced by the authenticity of them myself.
