Britney's Mom Visits K-Fed

Britney Spears' estranged mom, Lynne Spears, arrived by herself in Los Angeles late Sunday night . Her arrival coincides with today's report that the pop star and her mother are, once again, in touch.

Monday morning on The View, Barbara Walters revealed that she spoke with Britney's friend, Sam Lutfi, who told her he believes the pop star suffers from a treatable mental illness. Lutfi also confirmed that Britney and Lynne have been speaking again. (The two have been estranged since last summer.)

As for Lynne's plans to see her troubled daughter, an eyewitness says it may or may not be her reason for coming to L.A. The source confirms to OK! that Lynne spent Monday night at Kevin Federline's house, visiting with her two grandsons, Sean and Jayden.

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

In the meantime, Britney's been granted "telephonic communication" with her boys. In the latest minute report, commissioner Scott Gordon ruled "Petitioner is to have telephonic contact with the minor children in accordance with the parties' oral stipulation this date."

Britney was previously denied physical contact with the kids after her various meltdowns.
