'He Couldn't Be More Heartless'

Stay classy, Tiki. Your kids will really respect you for treating your wife with such dignity.

He was running around town with his young mistress -- while his pregnant wife spent a week in the hospital -- and yesterday, Tiki Barber got tackled.

The ex-Giants star was slapped with divorce papers over his shameless gallivanting with 23-year-old former NBC intern Traci Lynn Johnson.

"He couldn't be more heartless," said a friend of the gridiron great and his eight-months-pregnant wife, Ginny, whose Manhattan divorce suit cites tricky Tiki's "adultery."

"[Ginny] is very heavily pregnant and was last week ordered into the hospital on bed rest," the friend said.

"Meanwhile, Tiki has been spotted all over town with his new girlfriend while she was in the hospital.

"He was at the NFL draft and out dining with Traci."

Tiki, who already has two sons with Ginny -- A.J., 7 and Chason, 6 -- is now shacked up with the sultry Johnson in a Midtown love nest.

When ducking out of that apartment and into his car yesterday, Tiki refused to answer a reporter's questions and only flashed a grin when asked whether he had recently spoken with his wife.

Ginny Barber is also outraged that Tiki has been low-balling her in out-of-court negotiations over financial support, a family friend said.

"Tiki refused to give her anything close to what she needs," the friend said. "The reason she filed is that settlement talks didn't work."

In the meantime, he can pretty much kiss a television career goodbye.

Meanwhile, a source told The Post that the "Today" show has booted Tiki as a high-priced correspondent amid fallout from the scandal.

Representatives for both NBC and Tiki refused to comment on that claim.
