So you think you're Lady Gaga's biggest fan? Your hair bow is cute and all, and wow, is that disco stick home made? It lights up? Good job! But while you were off deconstructing a disco ball, rumor has it a Russian billionaire one-upped you -- big time. reports the stern-faced man in black leather SS-like garb in Lady Gaga's 'Alejandro' is actually a Moscow-based billionaire who is said to have paid the singer $1 million to appear in her latest music video. Yes, you read that correctly: ONE MILLION DOLLARS!

The 30-year-old mystery billionaire, identified only as "Arkady," is reportedly a huge Gaga fan (duh) who just couldn't live without being immortalized in her latest 9-minute mini-movie. When asked for comment, he responded, "Yes it was me in the clip, but I can't give further details." Obviously, the Lady has sworn him to secrecy, and we can't even begin to imagine what inventive punishment he faces if he breaks the vow. Relive his million-dollar cameo after the jump. >>>
