What's going on here!
U.S. swimmer Nathan Adrian was getting pretty cosy with fellow American swimmer Natalie Coughlin.
She certainly seems to be enjoying that back rub!
The two were spotted with another couple getting some late night grub after the Speedo party at Kensington Roof Gardens.
So we can assume they were drunk, but he should know she's married.
And she should know that's not cool, OBVI.
Wonder what's gonna happen when her hubby finds out…
