The long johns will form part of the "exciting" line, which he plans to launch next February, just in time for Valentine's Day.
Beckham is very proud to be fronting the venture.
"The underwear is totally my designs," he revealed.
"Things that I like to wear."
Beckham got the confidence to start the range after successfully fronting an underwear campaign for Armani for four years.
The stunning photographs shot by Mert Alas and Marcus Piggott, caused a spike in sales for Armani. However Beckham has revealed that the images of his new collection will be even better.
"The pictures are great. They are better" he acknowledged.
"Of course you have to step it up a little bit. They are my own underwear so of course they are going to be better."
