Justin TimberlakeJustin TimberlakeWe sometimes just stare longingly at the Showbiz Shed phone waiting for Justin Timberlake to call.

But alas, he never seems to dial our digits.

But he did make time to call a certain lady.

He dialled up Ellen DeGeneres on her show and pretended to be Mary Poppins, as a treat for El's 50th birthday.

We wonder if Ellen has a bit of a thing for the English accent?

He told Ellen: "I've been on your show a couple of times and I really think you're really sexy."

But he couldn't keep it up and his cover was soon blown: "It's hard for me to break into numerous voices - I get nervous and sweaty when I talk to you anyway."

What a cheeky monkey - it makes us love him all the more.
