Victoria Beckham feuding with daughter-in-law, Nicola Peltz

It’s the Ice Girls.

There’s a full-on cold war between Victoria Beckham and her new daughter-in-law, Nicola Peltz, Page Six has learned.

Peltz, 27, just married Brooklyn Beckham, 23 — Victoria’s oldest son with soccer superstar David Beckham — back in April. But we hear trouble was brewing even before the nuptials.

“They can’t stand each other and don’t talk,” a source close to the family told us. “The build-up to the wedding was horrendous.”

The source says that Peltz — who is the actress daughter of New York billionaire Nelson Peltz, a non-executive chairman of Madison Square Garden among other lucrative things —  didn’t want her soon-to-be-mother-in-law “to be any part of the planning, and she wouldn’t clue Victoria in on anything. Communication was minimal.”

Apparently, the cold shoulder didn’t help the iconic Posh Spice, 48 — who was struggling to warm up to the new member of the family as it was — see Peltz’s good side.

They added that it’s become “non-stop petty drama,” and it’s coming between the Beckhams — who now live in Miami — and their model son.

“They haven’t spoken to him much in the last few months,” said a source, who told us that it even went over badly at Chez Becks when Brooklyn posted a cover of British magazine Tatler that called Peltz “The New Mrs. Beckham.”

The sources suspect that Peltz — who has appeared in A&E drama series “Bates Motel” and in “Transformers: Age of Extinction” — may be suffering from a little jealousy about her man’s globally renowned mom, and isn’t thrilled with the attention she gets, especially around her wedding day.

So much for girl power…

Reps for Peltz and Victoria didn’t get back to us.
