The original California Girl! Kesha rocks a leather mini-skirt and sheer blouse to perform at Beach Boys charity event
She was a last minute addition to the Brian Fest line-up but that didn't stop Kesha making her mark on the charity event.
The California-born singer joined The Flaming Lips and Norah Jones at the night to celebrate the music of Brian Wilson of the Beach boys, to benefit Sweet Relief and the Jameson Neighborhood Fund.
Wearing a high-waisted leather miniskirt and sheer blouse, Kesha took to the stage with Brian to perform the classic California Girls at the Fonda Theater in Los Angeles Monday night.

Clearly enjoying herself, Kesha shared a picture with Brian the next day, captioning it: 'Got to meet the one and only brian wilson last night.'
Kesha replaced Brandon Flowers on the line-up, giving her time away from dealing with her current lawsuit lawsuit with producer Dr. Luke.
The latest from the courtroom is that now her former producer is demanding that she produce medical evidence to support allegations that he sexually and physically abused her.

According to documents obtained by TMZ, Luke is seeking to have the onetime chart-topper hand over records of all her communications in which she may have accused him of mistreating her.
However, the singer is reportedly against the idea, stating that as she's already asked a judge to throw out Luke's defamation lawsuit against her, the probe would be a wasted exercise.
Last week, Kesha had won something of a victory in their fight, as a judge decided that her claims of sexual assault took precedent over her alleged assailant's defamation suit against her.

A New York Supreme Court judge ruled that the pop star's California sexual assault case against Dr. Luke should move ahead first before considering his counter claims of defamation.
The defamation case, according to The Hollywood Reporter, has been put on pause until further notice.
The latest development comes months after Kesha filed a lawsuit for sexual assault and battery against Dr. Luke in October.
