Kate Hudson made her first appearance since it was announced she’s pregnant.

Hudson and boyfriend Matt Bellamy of the band Muse was spotted at Heathrow Airport in London today, where she kept her belly covered by wearing a loose sitting sweater and a big green winter jacket.

Though she’s still keeping her pregnancy under wraps, her mother’s longtime partner, Kurt Russell, is talking babies — telling PEOPLE “It’s fun having babies once again … and it’s fun to watch them grow. I think secretly we’re all hoping for a girl.”

This will be the couple’s first child together. Kate also has one son, Ryder, with ex-husband Chris Robinson.
