The Duchess of Cambridge Kate Middleton is not one to slack on her royal duties just because she is pregnant. The royal is set to visit Hope House, Action on Addiction in London, Feb. 19, according to a St. James Palace announcement. This will be Middleton's second official appearance since her pregnancy was announced.

The Duchess is a patron of the centre's programs that offers a safe and effective place for women to recover from substance abuse. It also helps patients with other issues like compulsive disorders. Middleton will be meeting the center's staff and clients and will also interact with women living in the center, reports US Weekly.

All eyes are bound to be on the 31-year-old who last made an official appearance at the BBC's Sports Personality of the Year Awards event in December. She also attended the unveiling of her portrait at the National Portrait Gallery on Jan. 11 but hasn't been seen publicly otherwise. The Duchess has taken up her official duties again, which means she has recovered from her severe morning sickness.

The mother-to-be had turned to lavender biscuits to ease the morning sickness and they seem to have worked. The flavor is said to have healing powers and very effective in keeping nausea at bay. The Duchess was earlier tucking into scones and strawberry jam but found solace in these biscuits since the morning sickness kicked in.

While Middleton might be busy attending to the royal duties and preparing for the baby due in July, Prince William is concentrating on his flying career with the RAF, but the royal couple intend to be "as hands-on as possible," a source told the site.

With this second appearance we cannot wait to see what the royal's maternity style is like.
