Jana Kramer is "annoyed" by her ex sharing their wedding day photo online—but not for the reason you may think.

On March 30, actor Johnathon Schaech took to social media to post about the duo's short-lived marriage. "I had to explain this photo to my son today," the That Thing You Do! star captioned a photo of the former couple's 2010 nuptials. "I told him I've been married three times. But I got it right when I married his mother. @kramergirl and I lasted a week. We weren't meant but for this photo and friendship."
