The "Batman Begins" actress - who has a two-year-old daughter, Suri, with husband Tom Cruise - sparked rumors she is expecting again after she was spotted wearing a loose-fitting shirt and long scarf to hide an apparent baby bump.

A source said: "Katie looked glowing and happy and kept placing a protective hand over her stomach. Even though she was trying to keep it covered, you could definitely see the beginnings of a bump."

Tom recently revealed he and Katie are planning to extend their family.

The "Valkyrie" actor - who also has two adopted children, Isabella and Connor, with ex-wife Nicole Kidman - said: "We'll have more children, I'm saying this but Kate's not here." Tom also said his experience as a parent helped when Katie gave birth to Suri.

He explained: "It was especially nice as it was Kate's first time. I've been around kids my whole life but it's different when they're yours.

"It's been very magical to have that and Kate is so calm and loving and Suri is the same."
