Ravens, take notice! Jana Kramer performed to One Tree Hill's theme song during her second week on Dancing With the Stars on Monday, September 19. The country singer, 32, played Alex Dupré on the beloved teen drama from 2009 to 2012.

But it gets better. Gavin DeGraw was on hand to sing his 2003 hit "I Don't Want to Be" live. The musician, 39, made a few cameo appearances as himself on the series back in the day. Kramer and her pro partner, Gleb Savchenko, received a 29 out of 40 score for her tango.

Kramer, who separated from her husband Michael Cassin last month — just seven months after giving birth to their first child, daughter Jolie Rae — has had a tough couple of days. Last week, she revealed that she strained her rib muscles during the season 23 premiere.

"I went to the doctors and found out that I have torn muscles in between my ribs. The doctor says I shouldn't dance," Kramer said on Monday night. "I'm very worried that we're not going to be able to get through the dance. I don't want to leave the second week."

The judges shared their support afterward. "First of all, you're a trouper. I know the pain that you're going through. Well done for just going out and giving it your best shot," Julianne Hough said.

Carrie Ann Inaba added: "This is when you realize that dancing is truly a sport because that was a difficult routine to get through. I could see your pain the whole time. … You gave it your all."

Kramer's former costars cheered her on, too. Laguna Beach alum Stephen Colletti, who played Chase on OTH, gave her a shout-out via Instagram. "You know who this soldier is voting for on DWTS tonight," the 30-year-old captioned a pic. "Best of luck to one of Tree Hill's own on DWTS. Sorry I couldn't be there for the OTH love, @kramergirl but #teamglamer support up. #othfamily."

OTH fan favorite Sophia Bush showed her support on Snapchat. "Duh!" the Chicago P.D. actress, 34, replied, when asked by a fan if she would be watching Kramer's performance. "You know she's dancing to Gavin DeGraw right? So many feelings! I'm so excited."
