Katie Holmes is reportedly pregnant with her second child, but while she and husband Tom Cruise are allegedly trying to keep it a secret, it's their daughter Suri who recently almost blew the lid on the news.
"[Katie's] struggling to contain the news! She can't wait to be a mom again, and the sooner she can tell the world about it, the happier she'll be," a source close to Holmes told Star Magazine.
Suri, who recently celebrated her 6th birthday, was turned to her Mom during a New York City visit to Newsies on Broadway and asked "if her baby sister was in Katie's tummy!" source said.
"Katie laughed and whispered something in Suri's ear," the source added.
The 33-year-old is a step-mother to Cruise's other daughter Isabella, 19, and son Connor, 17, both of whom he adopted with ex-wife Nicole Kidman. She believes that her new baby will have a positive impact on everyone.
"Katie thinks the baby will bring the family closer together," the source said.

While neither Cruise nor Holmes has confirmed the big news, fans expect that the couple, who have been married for six years, will shower their new baby with extravagant gifts as they have done with Suri.
During the Christmas holidays Suri raised eyebrows after it was reported that the six-year-old had given her parents a $130,000 Christmas wish List.
Tom decided to add $5 million - in honor of her milestone birthday - to Suri's trust fund. It has been reported that she already has several million in the fund.
The expensive list included $100,000 pony, which her famous father conveniently located a stable for near their home in Beverly Hills.
Also on the list was a set of $15,000 diamond earrings, and $1,500 gowns that will make her "look like a fairy princess," according to In Touch Magazine.
"Tom and Katie love the holidays and always go overboard…They are buying Suri absolutely everything she asks for," a source told In Touch.
