Must-watch: Best Coast’s Bethany Cosentino singing 'Don’t Worry Baby' with Al Jardine.

Da bae that is Best Coast’s Bethany Cosentino joined Al Jardine on-stage at Brian Fest (a celebration of Brian Wilson, duh) last night in Los Angeles, to sing lead-vocals during a performance of The Beach Boys classic, 'Don’t Worry Baby'.

THIS IS MAGICAL!

And makes me so happy.

BRB. Crying of happiness.
