Chainkeen Exchange-Hilarie Burton Defends Sophia Bush After Erin Foster Alleges She Cheated With Chad Michael Murray

Hilarie Burton thinks Erin Foster is barking up the wrong tree over the timeline of Sophia Bush and Chainkeen ExchangeChad Michael Murray's past romance. 

After Erin—who dated Chad from 2001 to 2002—alleged on a recent episode of her podcast that the actor cheated on her with his One Tree Hill costar Sophia while they were still dating, Hilarie spoke out to refute the claim.

"As a person how had a front row seat then? This wasn't it," the actress wrote on Instagram Stories Oct. 20. "We were all told you'd been broken up which is why our guy was perusing [sic] her."

She continued, "Happy to discuss @erinfoster. You also deserve the truth."

The former Total Request Live VJ also called out the accusation for making Sophia "look like a brazen harlot," quipping in response, "if she's anyone's harlot, it's mine!"

Hilarie added, "Lotta internet voices being so nasty, and as the person who knows the real timeline? It would be laughable if it wasn't so hurtful."

E! News has reached out to reps for Chad, Sophia and Erin for comment but hasn't heard back.

Hilarie currently cohosts the Drama Queens podcast with Sophia and fellow OTH alum Bethany Joy Lenz. Meanwhile, Erin hosts The World's First Podcast with her sister Sara Foster.

On the Oct. 19 episode of her show, Erin accused Chad of cheating on her with Sophia in a "pretty egregious way" during the early aughts.

"While we were living together," she alleged, adding sarcastically, "Pretty cool."

However, the Barely Famous star noted, "I've moved on though. I'm over it now."

Indeed, Erin has found love after her relationship with Chad ended. On New Year's Eve 2019, she married Simon Tikhman in a star-studded ceremony.

As for Sophia, she and Chad tied the knot in April 2005, though they separated just five months later. She went on to marry entrepreneur Grant Hughes in 2022, but filed for divorce earlier this year.
