*Tiki Barber thought he had more time to work on repairing his marriage before his pregnant wife officially filed for divorce – but he was wrong.

According to TMZ, the retired New York Giants running back was “floored” that Ginny Barber filed the papers on Tuesday yesterday — 30 days ahead of their game plan.

The Web site cites a source who claims Tiki was under the impression that he and his wife had put the divorce on hold, meaning neither “would file papers until after their [twin] babies were born.”

Tiki and Ginny have been separated since reports of his alleged affair came out weeks ago.
