Madonna has revealed how Quentin Tarantino turned down an invite to direct her music video.

The chart-topping superstar, whose new album MDNA is reigning high in the number one spot around the world, admitted she wanted the Kill Bill filmmaker to direct the music video to her single, Gang Bang, in a Twitter chat.

"He's shooting a movie til June. That's no excuse. I'm still waiting for his call. Every little thing..." she said.

When asked what she would do if she was invisible for a day, she added: "I would follow Quentin Tarantino around for a day and see if he is really too busy to direct Gang Bang."

Madonna - who was posed questions by celebrity friends Lionel Richie, Britney Spears (whom she asked for a kiss) and Katy Perry - also revealed how she wants to appear on US comedy show Saturday Night Live.

"FOR SURE. I'm gagging to do it. I'm obessed with Kristen Wiig and @AndySamberg. I want to do a skit with Kristen and Lola," she wrote.

And the 53-year-old, who was previously married to British director Guy Ritchie, admitted that she's partial to certain UK chocolates.

"Cadbury Creme Eggs. Don't get me started - they are so good," she added.
