Robert Downey Jr. is already on his way to becoming "Father of the Year."

The Sherlock Holmes: A Game of Shadows star recently took his six-months-pregnant wife Susan Levin on a romantic Hawaiian getaway. The couple -- who went snorkeling on the island of Kauai -- will welcome their first child together in February.

The spouses met on the set of Gothika in 2003 and married two years later. The Oscar-nominated actor has an 18-year-old son, Indio, with first wife Deborah Falconer. Downey, 46, credits his film producer wife with helping him stay sober after years of drug and alcohol abuse.

"There's no understanding for me of the bigger picture in real time in a hands-on way without her," he told Esquire in 2009. "Because it was the perfect, perfect, perfect matching of personalities and gifts."

Rest assured, Downey will be a hand-on father when he and Levin become parents in 2012 -- diaper duty included.

"That's just poop," the actor told E! News in October. "That's no big deal."
