Enjoying some well-deserved time off from her busy career, Miranda Kerr stepped out in Hollywood with her son Flynn this morning (April 11).

Sporting a big smile, the Australian poser looked very much the yummy mummy as she took her pint-sized boy to the Romp recreation center for some active quality bonding.

And while there are rampant rumors that Miranda was let go by Victoria’s Secret, who opted not to renew her contract, it seems Kerr was the one who stepped away.

An insider shared, “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.”

“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.”
