The Duchess of Cambridge showed off her growing baby bump during a public appearance Tuesday morning in London.

The 31-year-old Kate visited Hope House, a residential treatment center run by Action on Addiction. It marked one of her few official public appearance since announcing her pregnancy in December.

The former Kate Middleton, who just returned from a trip with Prince William to the Caribbean, donned a gray MaxMara Studio wrap dress, reports People.

"It's nice to be back," Kate said during her visit. "It's a lovely day for it."

According to People, Kate discussed her pregnancy with the women at the center.

Lisa, 34, a mother of three said, "I asked her if she was nervous about having a child, and she said it would unnatural if she wasn't. 'It's just human, isn't it?"

According to The Telegraph, Nick Barton, who heads Action on Addiction, described Kate as "intelligent," adding, "I speak of what I know -- somebody who wants to help, is helpful and genuinely interested and is intelligent...I've met her several times and I found her to be engaging, I found her very natural, I found her actually genuinely interested in the subject."

Kate is due to give birth in mid-July.
