Jennifer Lopez confessed that it would be a "blessing" to be a mother once again and said that she was open to adopting a child in a meeting with the press in Los Angeles to present her latest film, this one based on the best-seller about pregnancy "What To Expect When You're Expecting".

The 42-year-old singer and actress revealed details about how she fared during her pregnancy with twins Emme and Max, who have just turned 4, the physical changes she experienced, her memory losses, her post partum depression and how motherhood changed her life.

"I want them to be well, that is the main thing for me. The rest will come later. I'm going day by day," Lopez, who said she had "my hands full" with raising her children and was relying on the support of "a big family," said Saturday.

The artist is currently preparing a summer tour of North America with Enrique Iglesias and the duo Wisin and Yandel, and is a panel member on two television shows, "American Idol" and "Q'Viva! The Chosen, on which she works with ex-husband Marc Anthony, the father of her children, and to all of this may be added the May 18 screening of the new film.

"I'm a little tired," Lopez said.

The actress said she was happy with how things are going when she spoke at the press conference at the Four Seasons hotel in the presence of castmembers Cameron Diaz, Elizabeth Banks, Anna Kendrick, Wendi McLendon-Covey and the author of the book, Heidi Murkoff.

"What To Expect When You're Expecting" is an ensemble film that tells the stories of several different pregnancies, as gathered in Murkoff's popular work.

In the film, Lopez is in a relationship with Brazilian Rodrigo Santoro and together they decide to begin legal procedures to adopt a little Ethiopian boy.

The singer said that her role in the film opened her eyes to adoption, something that she had never thought about before.

Lopez divorced Anthony in July 2011 after seven years of marriage. She had given birth to their twins in February 2008.
