The cover hitting newsstands on Friday features Heigl seemingly praying for forgiveness with the large quote "I'm Sorry."
It's family, not film, listed as the official reason why the 31-year-old actress the actress sought to leave the show despite having 18 months on her contract.
“I started a family and it changed everything for me,” said Heigl in the extracts of the interview which have appeared online, “It changed my desire to work full-time.”
The star took a three-month family leave from Grey’s this season to bond with her newly-adopted daughter, Naleigh.
How sure a thing is her leaving? Here's a big sign. While she was supposed to appear in the final five episodes so as to bring the ending to a bang -- even that's not happening. The Jan. 21 episode will be her last as Dr. Isobel Stevens.
ABC Studios is even looking forward releasing a statement that "wishes her well."
"Everyone at "Grey's Anatomy" is now focused on delivering a shocking season finale and a great show for seasons to come.”
