LOST beauty EVANGELINE LILLY falls for production assistant after romance with co-star Dominic Monaghan and he’s NOT happy, The ENQUIRER has learned.

The freckle-faced Canadian beauty, who plays Kate Austen, has fallen hard for Lost production assistant Norman Kali after finally getting over her three-year romance with costar Dominic Monaghan, say sources.

"Lost certainly has been very good for Evie’s love life," noted a set insider.

"Her romance with Dominic ("Charlie") was red-hot for a long time, and they’ve still managed to remain friends. Now she’s found love again on the Lost set with Norman.

"I’m very picky when it comes to men," Evangeline said. "I come across a man who I’m really attracted to about once every five years."

Evangeline and Norman became friends working on the show and "in time that friendship blossomed into romance," said the insider.

"Norman’s everything Evie wants. He’s handsome, strong and buff. He loves the outdoors and has a great sense of humor."

One problem: Dominic is still in the picture. "It’s been hard for him to accept that Evie has moved on," said the insider.

When Dominic learned Evangeline and Norman hosted a party at her home in Hawaii, his ego was bruised.

"The next day on the set, he made some pretty sarcastic remarks about them in front of the cast and crew," the source said.

"It was awkward and embarrassing."
