And now David is following suit after signing a deal with clothing chain H+M to bring his "bodywear line" to stores worldwide.
He says, "Over the past year, I've been developing my Bodywear range with my team and I'm extremely positive about what we have designed and produced.
"The final piece in the jigsaw was a retail partner who has the vision and capability to distribute these products globally. In H&M we have found the perfect partner to collaborate with going forward."
The range will be distributed to 50 countries from February (12).
