A U.S. magazine is reporting on what they are calling the “shockingly lonely life” of Tom Cruise and Katie Holmes' daughter Suri.

The 'expose' of the tot's apparently solitary existence includes claims that the adorable 2-year-old is "trapped in an isolated bubble" because of dad Tom's distrust of other people.

Under the headline 'Inside Suri's Lonely Life', it's claimed that little Suri "only interacts with her parents" and "is rarely around children her own age" because "Tom's very picky about other people's kids."

"It's really sad. You can see how much Suri longs for someone to play with," a source tells Star.

"She does not interact well with [children her own age]. She doesn't like to share because she doesn't know how to — she never has anyone to share with!"

According to the tabloid, Suri has to make to with mum Katie and her dolls for company, as was the case when she visited Chelsea Piers in New York to play in its gym recently.

"Suri takes a private class in a room in the back of the gym," observed an employee.

"I have never seen her play with any of the other kids."
