Hot on the heels of Hot Tub Cinema and the newly announced Hot Tub Speed Dating comes Hot Tub Karaoke. Pretty self-explanatory, this one, but what you need to know is that tubs will be pitted against each other in karaoke battles, so don't think you can get away with a boozy, lazy version of 'I Will Survive' – bring your best, most energetic vocal performance (and your swimming cossie, obvs), as there are prizes at stake.
And if you've enjoyed watching films, speed dating and singing in hot tubs, hold on a little longer for what we think will be the next instalments in the series: Hot Tub Pottery Class, Hot Tub Paintballing and Hot Tub Spreadsheet Risk Management Seminar.
