Supermodel Miranda Kerr was not fired as a Victoria’s Secret Angel for “being difficult” but is stepping down because she could not devote enough time to the demanding brand, sources exclusively tell Page Six.

Talks between the lingerie line and the Australian beauty fell apart last week because VS was asking busy model Kerr to devote three months a year to promoting their sexy brand.

But a source with knowledge of the situation told us: “The problem was the time commitment. Victoria’s Secret usually asks the girls who are Angels to commit three months in a particular year to the brand.

“But Miranda has become a big star — she recently signed a deal with airline Qantas and has just replaced Kate Moss as the face of Spanish fashion line Mango,” our source continued.

“While she loves Victoria’s Secret, the time commitment they needed from her as an Angel became too much for her to fulfill. Exactly the same thing happened with Gisele Bundchen and Heidi Klum — their careers became huge, and there were other opportunities which made being an Angel full-time impossible.

“Anyone who says otherwise about Miranda, it’s just sour grapes. She is still going to walk in the show this year, and is still committed to the brand, but their relationship is evolving.”
