Robert Downey Jr. is enchanted by his wife's beauty

Actor Robert Downey Jr has heaped praise on his wife Susan Downey calling her "beautiful". Susan, a producer, is expecting their second child, and Downey Jr. feels she looks better than ever.

The 49-year-old star said: "This lady is so beautiful, she's just walking art."

The couple, who already has two-year-old son, Exton, met while making the ghost thriller “Gothika” in 2003 and got married in 2005. They are currently collaborating for the seventh time on the upcoming drama “The Judge” and love spending time together on set.

"It's nice to mix the two things I love the most," said Downey Jr.

Susan, 40, is due to give birth to a baby girl in November and admits the couple "couldn't be more excited".
