Channing Tatum and wife Jenna Dewan-Tatum were left ''mortified'' when they went for a couples massage.

The 'Witches of East End' actress wanted to treat her husband at a spa in Canada, but the pair were horrified when they discovered they would have to be ''butt naked''.

Speaking on 'Chelsea Lately', she said: ''In Vancouver, there's an Indian spa -- and they don't tell you this -- they take you in there and they put you in a sari and then they take it off, so you're completely butt naked.

''You're normally naked but it's [usually] like dark lighting. First of all, there were really beautiful Indian women, so already I was like, 'Maybe I'm regretting this.'

''And then I'm watching Chan be mortified -- this is the funniest part --because I'm sitting there in the steam so I go first and I'm like, 'Oh, he has no idea.'

''Like, she saw him just sitting there naked and then they bring him out and he's just completely naked, and she completely knows who he is, obviously.

''He looks at me like, 'I am going to kill you.' It was quite mortifying for both of us.''

Jenna - who has 12-month-old daughter Everly with her spouse - recently admitted the '22 Jump Street' actor doesn't like her filming sex scenes.

Asked if it was true her spouse ''doesn't like her having sex scenes with other men'' on TV, she said: ''So true.''

She added: ''It'd be weird if he was like, 'Ah, I'm cool with it, do whatever,' you know?

''It's never fun [shooting love scenes], but you just get really used to it, it's weird.''
