There's a whole lot of love in Jennifer Love Hewitt's household.

The actress welcomed a baby girl this week -- and has secretly tied the knot with beau Brian Hallisay.

"Jennifer Love Hewitt and her husband Brian Hallisay are thrilled to announce the birth of their daughter," a rep for the actress told us. The little bundle of joy's name is Autumn James Hallisay, and she was born on Tuesday. This is the first child for Hewitt, 34, and Hallisay, 35, former co-stars on the now-cancelled racy Lifetime series "The Client List."

In June, the couple of a little more than a year announced their engagement and Hewitt's pregnancy.

"This is a wonderful time and we are looking forward to starting our family together," they told us in a statement at the time.

In 2008, Hewitt called off her engagement to actor Ross McCall. She also dated her "Ghost Whisperer" co-star Jamie Kennedy, but split from him in 2010.
