Leona Lewis has accepted Michael Costello's public apology after she accused him of bullying.

Lewis, 36, wrote on her Instagram Story on Tuesday that Costello was hypocritical for saying Chrissy Teigen sent him hateful messages in 2014 because he had bullied Lewis that same year.

She said the designer left her feeling "humiliated" during a dress fitting for a charity fashion show by refusing to alter a sample-sized dress to fit her, and ultimately refusing to style her altogether.

"The pot calling the kettle black in this situation doesn't sit right with me," Lewis wrote. "Bullying comes in many different forms."

Costello later apologized to Lewis on Instagram. He said it was a misunderstanding and asked if they could have a "heart-to-heart" conversation about what happened in 2014.

Lewis responded to Costello on her Instagram Story on Wednesday, writing: "I love you guys so much for the support you've shown, there are always two sides to every story and that's clear here but I choose forgiveness.

"Michael, thank you for your apology, I wish you healing and that you feel better. For now today is a new day, spread love," she added.

Costello's representatives did not immediately respond to Insider's request for comment about Lewis' statement.

However, the designer released a statement to Insider on Wednesday, sharing his account of the dress fitting.

He said he was given seven days' notice before styling Lewis for the event, and that the singer appeared unhappy with the dress choices he presented her with.

"If Leona has been harboring misunderstandings and hurt all these years, I wish she would've talked to me directly," Costello told Insider. "My team was open in communicating with her team. Even a year later in 2015, she posted herself in one of my dresses on her on Instagram."

Costello added that he was "blindsided" by Leona's comments "because the story she shared on Instagram paints a very different picture than the one she led me to believe for years."

Representatives for Lewis did not respond to Insider's request for comment.
