Britney Spears’ estranged mother, Lynne, arrived by herself at LAX, Sunday night. Her arrival in L.A. is sparking reports that the pop tart and her mother are talking again.

While we’re not exactly sure why Lynne Spears came to L.A., a source reveals that Lynne spent Monday night at Kevin Federline’s Tarzana home, spending time with her two grandsons, Sean and Jayden.

Lynne also may have been in town to tie up some loose ends. Her and Jamie Lynn are reportedly getting rid of their Valencia home to live full time in Kentwood, La.
