Hollywood is full of plenty of rude and demanding stars, but according to insiders, some of those celebrities aren't even human. Humans in the know say that in fact, the canine star of the movie 'Men in Black' was one of the most demanding celebs out there.

Fans will recall that Frank the pug (who was actually an alien) was a highlight of the movie 'Men in Black.' Of all the characters that were cast, the pug was one of the biggest hits.

Sure, Will Smith and Tommy Lee Jones were great, even though one 'Friends' actor almost made the list instead, but Frank was a knockout.

Like other famously pampered pooches (such as Paris Hilton's), the dog behind Frank was truly one of the elite.

Mushu, the famous dog who played Frank, passed away years ago, noted Northern Star. But during his celeb status on 'MIB,' he received tons of special treatment. The owner of the dog explained that Mushu only traveled in Business Class, with his trainer by his side.

While Mushu did travel under the seat, once he arrived on-site to start filming, that's where the pampering started. The owner, Cheryl Shawver, said that Mushu stayed in the hotel room with his trainer while filming. He also slept on her bed.

But what's more, noted Northern Star, Mushu got whatever he wanted via room service. The trainer would order him food like chicken and steak, delivered piping hot to his room.

Mushu also only drank bottled water while he was on the road, said his owner. No explanation for why that was, when dogs in film are known for slurping out of toilets. Clearly, Mushu was above that type of behavior.

To sum up, Mushu's human explained that he was a "VIP." But that doesn't mean he had a poor attitude on set. Unlike celebs who often request tons of pampering, Mushu apparently made it easy on the cast to get the takes they needed.

He was an adorable part of the first 'MIB' film, and then Mushu returned for 'Men in Black II' with even more hilarity. Technology wasn't as amazing as it is today, but the producers were able to take Mushu's footage and make it look like he was talking, with Frank snapping off quips and singing along to "I Will Survive" and "Who Let the Dogs Out," noted Extraterrestrials Fandom.

Unfortunately, only Frank's (well, Mushu's) likeness was only involved in 'MIB 3,' in the form of a portrait on the wall. But fans won't ever forget the adorable pug, and the show's behind-the-scenes crew probably won't remember his demands for luxury while on the road.
