Kate Middleton isn't letting a little thing like pregnancy get in the way of her royal duties.

St. James's Palace announced on Tuesday that the Duchess of Cambridge will visit Hope House in London on Feb. 19.

Prince William's other half is a patron for the facility's program, Action on Addiction, which offers a safe and secure place for women to recover from substance dependence and receive additional support for other compulsive disorders.

The visit to Hope House will be Middleton's second official appearance since becoming pregnant. On Jan. 11, she and her husband attended a private viewing of the duchess's first official portrait at London's National Portrait Gallery.

What's more, it will be the first since her baby bump debut last weekend as she shopped in West London.

Middleton is due in July.
