Have Britney Spears and Kevin Federline reunited? The former pop princess and the lone member of the 'Brit Pack' not in jail or rehab spent some time in Mexico on vacation recently and according to NW Magazine told her pals that after weeks of hush-hush meetings and tearful late-night discussions, she is set to reunite with her ex-husband Kevin Federline.

Britney Spears & Kevin Federline Back Together?

Wait - what? Kevin and Britney finalized their divorce earlier this year and she has been in rehab and is now attempting to revitalize her sagging career. Is this the time to get back with K-Fed?

"When she was on vacation she was in the best mood she's been in for ages, " an insider dished to the magazine. "She confessed it was because she and Kevin are slowly moving towards getting back together. "

The report claims that after months of misery and confusion, the singer has welcomed Kevin back into her life. Pals were stunned when Brit told them her news, as it seemed reconciliation was the last thing either of them wanted after their divorce was finalized in March. Even more shock - the report claims that each time Kevin drops off their sons Sean, 21 months, and Jayden, nine months, he stays for hours — and sometimes even overnight.
