Katie Holmes has sparked rumours that she may be expecting her second child with Tom Cruise.

The actress was photographed wearing loose-fitting clothing to hide what appeared to be a baby bump, according to reports.

“Katie looked glowing and happy and kept placing a protective hand over her stomach," a source told New magazine.

"Even though she was trying to keep it covered, you could definitely see the beginnings of a bump.”

The couple have previously said they were keen to have a brother or sister for two-year-old daughter Suri.

"We'll have more children. I'm saying this but Kate's not here," Cruise said recently.

The actor also has two adopted children with his ex-wife Nicole Kidman.
