Did Jim Bob and Michelle Duggar blatantly lie about their daughter's profession? According to some fans, they did and those fans are letting the family hear it!

The Duggar furor stemmed from a social media post on twins John and Jana's 25th birthday where the parents praised their children and called their daughter a "concert pianist."

"They both have a ministry heart and are great role models for other young people," the post on the family's official Facebook page said, with a picture of the birthday kids. "John just finished up his pilot's license and is staying busy with construction and police work. Jana is a concert pianist and is involved in many ministries. We are so blessed to have such wonderful daughters and sons. Happy 25th Jana and John!"

"Concert pianist." Those two words sent many fans into a rage because classical music is a very competitive field, and they don't believe Jana is nearly qualified to earn that title. Jana, fans said, is not a concert pianist.

It's probably safe to assume the family didn't anticipate this feedback when they posted the photo of the twins celebrating their birthday at an Arkansas Cracker Barrel.

One fan wrote, "Um …. 'concert pianist'? You need to check out what that really means. People study and practice intensively and dedicate themselves for years and years to earn that title. Sergei Rachmonivov and Arthur Rubenstein ... now those were 'concert pianists.'"

We can't confirm, nor deny, what Jana's career is or isn't, but there are definitely two words that the "19 Kids and Counting" family willingly admits they know nothing about: birth control.
