Fans still wild over Minaj

US rapper Nicki Minaj has pioneered a very personal new form of merchandise.

As part of her first Australian tour, Minaj offered fans a VIP meet and greet package that included selling her now trademark "boob signings".

But for the first leg of her debut world tour Minaj's sold out Hisense Arena show last night was a little underwhelming compared to her contemporaries like Rihanna and Lady Gaga.
