Charlize Theron claims she was tricked into performing at the Oscars.

She admitted: "I thought it was going to be something smaller, like he pulls me up from the audience and we do a little spin.

"But then he was like, 'Rehearsals start Monday!' "

While Charlize was terrified ahead of the performance - which saw them waltz while Seth sang 'The Way You Look Tonight', she had a great time thanks to her "wonderful" partner.

Asked what the experience had been like, she told E! Online: "Completely nerve-wracking. But how could I not dance with Channing Tatum? He's so wonderful!"

And the actress joked Channing - whose wife Jenna Dewan is expecting their first child - was too "classy" to wear anything but a tuxedo on stage at Los Angeles' Dolby Theatre, despite his movie success in stripper film 'Magic Mike' last year.

She said:"No [he shouldn't have stripped]. He's so classy--and he's about to be a dad!"
