Sonny Bill Williams joins celebs in cupping craze
SPORTS star Sonny Bill Williams has embraced the latest celebrity pampering craze: cupping.
Gwyneth, Madonna and even Posh Spice do it.
Now SBW has taken to Twitter to show off a posterior that looks like a well-used coaster.
"Tried a lil [sic] cupping yesterday woke up looking like this."
Cupping is a Chinese alternative medicine which uses suction to mobilise blood flow and promote healing.
