A.J. McLean dons nappy for baby shower costume

Backstreet Boys star A.J. Mclean hosted a party with a difference for his pregnant wife over the weekend - all the guests dressed as babies.

The singer and his wife Rochelle Karidis are expecting a daughter in the coming weeks, and to celebrate her impending arrival, the couple threw a themed baby shower.

McLean's bandmate Kevin Richardson was among the guests, and wore a blue one-piece, while the dad-to-be sported an oversized nappy.

McLean has uploaded pictures from the event to his Facebook.com page and says in a video, "Today I am loud and proud as you can see in my little baby outfit for my wife and I's baby shower."
