With a reputation as one of showbusiness's greatest divas, Mariah Carey sure doesn't disappoint.

She still managed to turn up more than an hour late for a meeting with the Press to launch her new perfume - after the original time had already been delayed anyway.

And the sexy songstress headed off to the new Jalouse nightclub afterwards for a party to celebrate the launch of her album, Memoirs of an Imperfect Angel, for which she was apparently three hours late.

Anyway, those rumours you've heard about her having an assistant for everything, from carrying her handbags to pampering her pooches...

Well, she came unencumbered by accessories, apart from a beefy boy toy who didn't just escort her to and from her seat in an opulent back room at the Dorchester on London's Park Lane, but practically held her up while she tottered along.

When Mariah finally did manage to make it to her seat opposite T4 host Rick Edwards, she talked for a grand total of six minutes. And this is what we learned:

*Mariah and her team went to her bathroom for inspiration for the flacons encasing the new perfume, because that's where she houses her collection of perfume bottles in her "old Hollywood" home with a "Deco vibe" in LA.

* Mariah went "back and forth" trying to choose a name for the new scent until Elizabeth Arden announced it had been saving the trademark 'Forever'.

* She "doesn't like the back seat" and said she was told she was the most involved in the creation of her fragrance with Elizabeth Arden, out of other celebrity and designers names.

* The pop princess describes the new fragrance as "breezy, light, feminine - delicate, darling!". And it is definitely not overwhelming, which was very important to the star.

* Despite Boots being the perfume's exclusive retailer currently - it's available in just three London stores and online until February - Mariah does not have a Boots Advantage Card. But she would like one.

And then, back came the beefy boy toy to help the undoubted diva teeter back out to her suite, stopping for just a few photographs on the way.

Spying my broken foot, Mariah whispered to me behind her hand that it must help get me into nightclubs. Not if I have to wait three hours for the star turn, it doesn't.
