The Hollyweird love story of rocker Chris Martin, estranged wife Gwyneth Paltrow and his girlfriend Jennifer Lawrence has gotten wilder – with the “Hunger Games” beauty now reuniting with ex-boyfriend Nicholas Hoult!

“Jen is definitely two-timing Chris with Nick!” an insider exclusively told The National ENQUIRER. “They got together when Nick was in L.A. in January to promote his new ‘Mad Max’ movie.”

The 24-year-old Oscar winner and Nick, 25, split in early 2014 after three years together.

JLaw began dating the Coldplay frontman, 38, last August after he and Gwyneth made the announcement that they had “consciously uncoupled” after 10 years of marriage.

But Chris and Gwyneth keep staying entangled, and spent this Valentine’s Day together on the beach in Malibu with their kids, Apple and Moses.

“Jen and Chris got into a big fight over Nick, but Jen’s standing her ground,” said the insider. “She figures what’s good for the goose is good for the gander!”

Jen first met Nick on the set of 2011’s “X-Men: First Class.” They’ll soon begin filming “X-Men: Apocalypse.”

The source added: “Jen’s frustrated with Chris’ unwillingness to commit. Now she’s keeping her options open.”
