Jana Kramer Fan Proposes to Already-Engaged Singer!

Jana Kramer already has a beautiful rock on her left hand, courtesy of fiancé Brantley Gilbert, yet the "Whiskey" singer accepted another marriage proposal Monday night!

It all happened right on stage during KFDI Radio's Concert for Kids in Wichita, Kansas. Prior to arriving, Jana received a tweet from a fan who told her he wanted to propose to her while she was in town. The brunette beauty replied that she would welcome the popped question, but only if he did it onstage at the show. In exchange, she promised to make a $100 donation to St. Jude Children's Research Hospital, the charity the concert was supporting.

When Jana stopped her show to ask for the young man to come on stage, he became very shy and didn't stand up, so his wife (yes, wife) pointed him out to the singer. When Jana found out the young man already had a sweetheart, she acted heartbroken. "What! You are married?" she said as he finally came forward. "I'm engaged, you're married, come on up!"

Amid much applause and laughter from the audience, the fan finally took Jana's hand and told her, "You are the most beautiful woman in the world." One of Jana's band members brought her a box of tissues and she immediately took one and started fanning herself with it. This cracked the young man up and he could barely get out the phrase, "Will you marry me?"

Jana's reply was a prompt yes. She thanked the young man for coming forward and for doing something extra to help the kids at St. Jude. Then she announced that she was donating more money than she had promised: $500.

"Oh God, Brantley's really gonna get mad at me," Jana said jokingly as fiancé No. 2 made his way back to sit beside his wife.

The concert was the kickoff for KFDI's "Country Cares for St. Jude Kids Radiothon." Country stations around the nation participate in a tradition started by Randy Owen of Alabama years ago, when he challenged them to hold events to raise money for the children's hospital in Memphis.

Jana is an accomplished actress, known for her role of Alex Dupre on "One Tree Hill." She left the show in 2012 to pursue her career in country music. She and Brantley -- both ACM nominees for Best New Artist -- were engaged on Jan. 20 of this year, Brantley's birthday.
