Pregnant reality star Kim Kardashian has fuelled rumours she's expecting a daughter with rapper Kanye West - the invitations to her baby shower feature a dancing ballerina.

The socialite's sisters Kourtney and Khloe are hosting a special bash for the mum-to-be on 2 June (13) and they spared no expense when sending out the party invitations, which appropriately contain music boxes that, when opened, play West's song Hey Mama and put into motion a twirling toy ballerina, according to

The over-the-top mailings have prompted many to suspect the socialite and fashion designer is planning for a girl, especially since photographers snapped multiple photos of Kardashian's assistant carrying a pink-themed baby gift basket into her home in April (13).

Actress-turned-Tv host Kathie Lee Gifford, who is the beauty's godmother, first sparked speculation the couple was expecting a girl on U.S. breakfast show Today in February (13), when she said Kardashian was "four months pregnant, I think now with her little girl".

The stars are set to become first-time parents in July (13).
