The 'Where Have You Been' star bursts out laughing as she admits her Twitter photos are "dumb".
Rihanna has unveiled a bare-faced picture of herself on Twitter.
The singer posted the candid picture shortly before she left Hawaii on Monday (30th April), where she had been promoting her new movie Battleship.
The photo features four separate images of Rihanna without make-up, including two with her struggling to contain her laughter.
In a message that accompanied the picture, RiRi said: "Just realized how dumb u look takin self pix on iPhone thanx to @leandra246."
RiRi visited Hawaii alongside other cast members from Battleship, which was released in cinemas around the world last month.
The 'We Found Love' singer also used the trip to catch up with her friends and was spotted paddle boarding in the sea.
Meanwhile, Rihanna released the video for her new single 'Where Have You Been' on Monday.
