In the course of the celebrations, Urban took to the stage. He was joined by Taylor Swift in a private concert of sorts. The duo gave such a rendition of Swift’s “Shake It Off,” and the crowd just went berserk. Hollywood Life informs that while Urban was amazing with the guitar, as usual, Swift too held her ground when she joined him, playing the guitar herself.

At one point, Reese Witherspoon took to the stage herself to sing along to “Sweet Home Alabama,” states Huffington Post. Her friend shared the moment on Instagram and captioned “You can take the girl out the South, but you can’t take Sweet Home Alabama out the girl!”

The party, which kicked off at 7:30 in the evening, went on till 2:00 a.m. Sources close to claim that Witherspoon was in her best mood when she left. “It was a great party,” revealed the sources to “When Reese left at 2 a.m., she was in the best mood. You could tell that she had the best time celebrating her birthday,” they added.
