Joan Lunden (search), a new mom at the age of 52, has ended her three-year relationship with A&E.

Lunden's series, Behind Closed Doors, will continue to air throughout the summer, and there's a chance she could work with A&E in some capacity after that.

"Officially, her contract is up with A&E, but there's a possiblility we could produce some upcoming specials [with her] in the near future," a network spokesman said.

The question remains when she will return to work now that she has two new babies -- or if she plans on giving up her career.

Lunden co-anchored ABC's Good Morning America from 1980 to 1997, first with David Hartman (search) and then with Charles Gibson (search).

She had a syndicated daytime talk show in development in 1998, after leaving GMA, but that show never got off the ground.

Lunden then inked her A&E deal in May 2000. Behind Closed Doors is a documentary series about what it's like in hard-to-get-to places, such as the cockpit of a fighter jet and an emergency room.

Lunden and her first husband, Michael Krauss, have three grown daughters, Jamie, Lindsay and Sarah.

Lunden and her new husband, Jeff Konigsberg, had girl-and-boy twins this week via a surrogate mother. They're the first children for Konigsberg.
