Brit Gets a Visit from K-Fed

Kevin Federline visited Britney at her rehab facility on Wednesday, and as he left, a photographer caught him deep in thought ... er, deep for K-Fed.

While most fathers of four would be busy planning birthday parties for their kids, the Fed-Ex is busy planning his own!

Looks like K-Fed's got his hands full, with a trainwreck ex in rehab, divorce proceedings, another ex and kids, and a hovering mother-in-law ... oh, and being unemployed.
