Robert Downey Jr. and Pregnant Wife Susan Vacation in Kauai

Robert Downey Jr. and Susan, his wife of six years, snuck away for a tropical vacation to Kauai last week. They strolled along the beach hand in hand on Friday, and Robert showed off his paddle-boarding abilities in the water on Saturday. The couple continued their Hawaiian adventures yesterday when they were spotted kayaking down a river. Susan didn't let her pregnant belly get in the way of the fun since she rowed right alongside her husband.

In August, Robert and Susan announced they're expecting their first child together, and she showcased her bump on the red carpet just last month. The upcoming family addition isn't the only project RDJ has in the works as he's also gearing up for the holiday release of Sherlock Holmes: A Game of Shadows. It's just the beginning of an exciting few months for the actor since the baby is due in February and The Avengers comes out in May.
