Britney Spears is heading home today for a big reunion with her younger sister, Jamie Lynn, LIFE & STYLE WEEKLY reports. The occasion? Jamie Lynn’s baby shower!

BRITNEY SPEARS’S HEADING HOME — FOR JAMIE LYNN’S BABY SHOWER!

Britney is leaving LA today to arrive in Kentwood, La., in time for tomorrow’s baby shower at mom Lynne Spears’ house, Serenity. Britney was last seen in Kentwood in November 2006. “The shower’s on Saturday at Lynne’s house,” the insider tells Life & Style.

“At first, Jamie [Brit’s dad and also her guardian these days] didn’t think it was a good idea for Brit to go. He thought it might create chaos in Kentwood, and he wasn’t sure he wanted to put Jamie Lynn — or Britney — in the middle of that.”

“Britney can’t travel without Jamie’s permission, so she worked really hard to talk him into it; it was so important for her to be there for her little sister. He finally gave in, knowing it’d be good for Brit and Jamie Lynn to finally see each other.”
