Britney jeting to New York for X Factor announcement!!!

Britney Spears is set to make a big splash Monday by personally appearing at the FOX Up Fronts in New York City for the announcement that she will be joining "X Factor."

As we reported, as of Friday AM the deal was NOT signed, contrary to various reports. There were some fairly minor issues that still needed resolving and both sides were hoping to finalize it by end of day Friday or over the weekend.

Britney will not sign the deal because she's under a conservatorship -- Co-conservators Jamie Spears and Jason Trawick will do the honors.

Our sources say ... Britney and FOX both think a personal appearance is essential in creating buzz
for the show.
