Is Onion really a canine celebrity?

How do you know if you're living with a real-live celebrity? We had a good think about this, as Onion seems increasingly convinced that's what she is. We concluded that to be part of the celebrity culture you should
1. be in a movie (Onion is in Scenes of a Sexual Nature)
2. have a pop career (Onion appears in A-ha's 'Cosy Prisons' video, see above and YouTube)
3. behave like a diva!
In which case, Onion definitely qualifies. Time to bring out an Onion perfume?!
