Keith Urban Sings ‘Sweet Home Alabama’ with Reese Witherspoon

Reese Witherspoon celebrated her 40th birthday over the weekend with quite the star studded affair, but there was one major thing that happened that now leaves me wishing I was Reese Witherspoon. 

I wonder if Keith Urban was an actual party guest who just picked up a guitar and crashed the stage, or if he was a surprise performer for the birthday girl. Either way, I'm jealous.

You can take the girl out the South, but you can't take Sweet Home Alabama out the girl! HAPPY BIRTHDAY @reesewitherspoon ❤️ (cc @keithurban)

The Los Angeles party also included a private concert from Taylor Swift, and lots of celeb power. As you can tell Kate Hudson had a pretty fabulous time as well...

When you take a shit load of pictures and you still don't have it perfect so you go for the ole collage post.... Happy Birthday gorgeous girl @reesewitherspoon !!!
