Britney Spears is heading home for her pregnant sister Jamie Lynn’s baby shower.

The ‘Toxic’ star is reportedly leaving Los Angeles later today to arrive in Kentwood, La., in time for tomorrow’s bash at mom Lynne Spears’ house, Serenity. Britney was last seen in Kentwood in November 2006.

An insider tells Life & Style magazine: “The shower’s on Saturday at Lynne’s house.

“At first, Jamie [Britney’s dad] 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.”
