Jason Sudeikis ''rehearsed'' a three-way kiss with Will Poulter for 'We're the Millers'.

The 37-year-old funnyman has joked he locked lips with his 20-year-old co-star to prepare for a raunchy scene in the comedy in which Poulter kisses both of his female co-stars, Jennifer Aniston and Emma Roberts.

Quizzed if he felt he missed out on the steamy three-way kiss, he quipped: ''On camera, I missed out [but] you've got to rehearse those things. I rehearsed with Will ... I know, I went the wrong way! The guy's forgot more about kissing than I'll ever know.''

The actor-and-comedian is engaged to Hollywood beauty Olivia Wilde, 29, and previously dated 'Mad Men' star January Jones, 35, and credits his witty charm for helping his love life.

Speaking to BANG Showbiz, he said: ''I think everyone's attracted to humour. Everybody likes to laugh - it doesn't matter if you have a penis or a vagina. Everyone likes being around somebody that's funny, and I think everybody likes making others laugh and laughing with people.''

Jason also praised his 'Millers' co-star Jennifer - who he previously worked with on 'Horrible Bosses' - describing her as a ''great listener''.

He said: ''She's a great listener. She's a great listener and she knows when something isn't working and always wants to make it better.''
