A picture of Matt, Lucy and Isabella in New York is at People.
BABY'S DAY OUT
New parents Matt Damon and Luciana Bozan make their first public outing Tuesday with daughter Isabella (born June 11), showing her the sights and sounds of New York City.
There are various other photos, including one of Lucy with Isabella in the stroller from recent weeks, at Just Jared. Thanks to Stephanie.
A caption at Splash News (to the recent pics of a solo Matt) confirms that Matt is in New York for filming (most probably re-shoots on The Departed).
Matt Damon returns from a workout and heads to his hotel in downtown Manhattan. He said he is in town to do some filming.
For those interested, Celebrity Baby Blog has details of the Bugaboo baby stroller used by Matt and Lucy in NY and Miami.
