The 30-year-old English model, who's pregnant with the couple's second child, sported her new diamond ring during a dinner date Sunday at Madeo in Los Angeles.

The Sherlock Holmes director and Ainsley have been dating since April 2010, two years after his split from Madonna after eight years of marriage. They initially confirmed the news of their second child when Ainsley showed off her baby bump during the premiere of The Dark Knight Rises in London in July. Their first son, Rafael, was born in September 2011.
