Pregnant Liz Hurley jetted from London to Los Angeles for a showdown with ex-boyfriend Steve Bing over their baby’s future — only to be cruelly snubbed by the reluctant dad-to-be.

So the three-months-pregnant damsel in distress turned for help to her old Sir Galahad — Hugh Grant!

Tearful Liz phoned Hugh in England — and he hopped a Concorde to be by her side as the party-hearty playboy she’s dubbed Bing Laden skipped town.

Liz, 36, and Hugh, 41, huddled at an L.A. restaurant together to discuss tactics.

Now Hugh’s vowed to back the beauty all the way in her battle to get Bing to face up to his responsibilities as a father.

Gallant Grant is even demanding a man-to-man meeting with the skirt-chasing movie producer, say sources.

“This plot’s getting crazier than any movie Hugh or Liz has been in,” declared a showbiz insider who knows the couple.

“Bing knew Liz was heading for L.A. to see him, but he picked that time to leave town with his buddy Mick Jagger so they could party in Las Vegas for a couple of days.

“Liz was distraught, and she turned to the only man she trusts now — Hugh.”

Last week The ENQUIRER revealed exclusively how ex-beau Hugh was trying to woo back Liz after Bing — heir to a $600 million real estate fortune — told her he didn’t want to be a dad.

“Hugh dropped everything to fly to her in L.A.,” disclosed an insider. “That’s how much she means to him.

“He hopes by being there for Liz she won’t be able to imagine a future without him.”
