Gwyneth Gets Emotional at Coldplay Concert

After nearly five years of marriage, Chris Martin can still bring Gwyneth Paltrow to tears -- which is exactly what he did at Coldplay's recent concert in New York City.

As his biggest fan, the 35-year-old actress was front and center for the band's concert and enjoying every minute of it.

"Gwyneth was whispering and clapping throughout the show," an eyewitness tells OK!.

But when Chris, 31, launched into "Fix You," the song he wrote for Gwyneth after her father Bruce's death in 2002, "she broke down in tears."

The tears didn't go unnoticed. After the show, Chris, 31, made sure to comfort his wife.

"He noticed she had been crying," the source says. "He kissed her and made her laugh by pointing out all the things he'd screw up in the show."
