Beyonce may be “with child” and everything … but it looks like that isn’t stopping her from slowing down with her “celebrity” duties anytime soon!

After a whirlwind week in New York City last week for this year’s New York Fashion Week festivities, Beyonce and her mother Tina Knowles, both dressed in all black, launched their House of Dereon clothing line in the UK Saturday (Sep 17) at London’s Selfridges store.

Also spotted at the launch event were “X Factor” 2008 winner Alexandra Burke and actress Rosario Dawson.
