Heavily pregnant performer Alaine Kashian has YouTube hit on her hands with her cover of Beyonce's Single Ladies.

Dressed in a leotard and heels while 38-weeks pregnant, Kashian swivels her hips through Beyonce's signature dance moves, while singing her self-penned "Pregnant Ladies" tribute, with the chorus amended to,

If you liked it then you should have put a thing on it/
Don't be mad when you say you have to baby sit

Other lyrics refer to the common pregnancy complaints of water retention, pelvic pain and loss of libido.

Beyonce could do well to pay attention to the words, with her own baby due early next year.
