Rita Ora’s decision to wear a bright white dress for her “Tonight Show” performance was more than a mere fashion statement.

It was also an effort to provide a canvas for street artist Mr. Brainwash, who joined Ora for Tuesday’s number on NBC’s “The Tonight Show Starring Jimmy Fallon.”

As Ora’s live rendition of new single “I Will Never Let You Down” approached its climax, Brainwash, born Thierry Guetta, started dripping red, yellow and blue paint all over the singer-songwriter.

Ora proceeded to smear the paint over her body as she assured the Tuesday “Tonight Show” audience of her unwillingness to let them down.
