Britney Spears and Kevin Federline have been married just over a year. They just had a bouncing (and adorable) baby boy and everything should be going great. But a report from the UK says the young couple's marriage may be in serious trouble.

It's from the British tabloid "News of the World" and the claim is that Brit is "fed up being stuck at home with new baby Preston while(Kevin) goes drinking with his pals."

Marriage Trouble for Brit and Kevin?

Writer Rav Singh reports:

My source tells me: "They have been rowing non-stop since the baby was born last month. Britney feels Kevin isn't supporting her and is just going out with friends all the time. She's had enough of it.

"He behaves like he's got no responsibilities while she is at home caring for their newborn son."

The tab even gives a hint as to why Brit "freaked out" and pulled the plug on selling the baby pictures of Sean Preston.

"Britney had done a multi-million-pound deal for the exclusive pictures but suddenly withdrew them as the couple were pictured as a happy family and there is now a wedge between them," another source reportedly close to the couple dished to NOTW.

A small contact sheet of those photographs were leaked and published on the Internet last week.
