WWW- COULD it be that legions of Britney Spears fans are finally going to get their wish, and that the pregnant pop tart is ready to dump her hubby of two years, the underemployed and overspending Kevin Federline?

Spears was said to be distraught that Federline didn’t spend Mother’s Day with her, opting instead to hang out with his ex, Shar Jackson, who has two children by him.

A furious Spears then fled California for New York with her infant son, Sean Preston, where she had a disastrous time.

In the city, Spears, pregnant with the couple’s second child, was continuously followed by a pack of paparazzi who caught her waltzing into Tao restaurant at 9 p.m. with her cranky baby and a pal – and leaving an hour later when he proved inconsolable.

The next day, a tired Spears tripped on her pants and almost dropped her young son – all caught on camera – and was later snapped sobbing at a deli.

“She felt drained and bombarded,” our source said. “She is not very comfortable in this city, and New Yorkers didn’t make her feel welcome. She has said she will never come back unless she has to.”

Spears was also embarrassed during her appearance on “The Late Show With David Letterman,” when she stumbled while reading several difficult words in Letterman’s “Top Ten” list.

During her trying week, Spears was angry that she was alone and Federline was not with her.

“Kevin’s focus has been on everything but Britney. Instead, he has been putting all of his energy into his music career – which isn’t going to go anywhere,” our source said.

“Brit is definitely unhappy in this relationship and feels stuck.”

In the beginning of the week, Spears also seemed to threaten Federline by printing a thinly veiled poem on her Web site about the “sins of the father.”

The poem, accompanied by a picture of a thin Spears and five friends giving the finger was taken down for a few days – but put back up by the end of the week – a sign insiders say which bodes ill for the marriage.

Until recently, Spears had been indulgent with her husband – supporting his music career, and flying him and his friends to Las Vegas to party. But now she has him on a strict budget and curfew. Spears’ rep didn’t return calls.
