Robbie Williams has vowed to have ''a lot of live sex on stage'' during his 'Take The Crown' tour this year.

The 39-year-old singer - who has six-month-old daughter Theodora 'Teddy' Rose with wife Ayda Field -has promised fans there will be ''nudity'' during his Amsterdam gig in July and joked he will be engaging in sex with himself at the show.

He quipped: ''I plan to do a lot of live sex on stage and I am practising by having a lot of un-live sex, but it didn't work out very well.

''There is lots of me singing my songs and live sex.

''I can promise you nudity and the sex will be with myself.

Olly Murs will support Robbie on the tour and while the 'Candy' hitmaker insists he will not be getting jiggy with it with the former 'X Factor' star, he joked he would entertain the idea if it meant selling more tickets for the show.

Speaking to The Sun newspaper, he quipped: ''I am not having sex with Olly ... I might do if it sells more tickets.''
