Just one night after Demi Moore was rushed to the hospital for inhaling too much nitrous oxide -- Ashton Kutcher hit up a Bruno Mars concert in Brazil ... where he fist-pumped his brains out.
The video was shot the same night Ashton dropped by a nightclub in Sao Paulo with a mystery female companion in a red shirt -- the same girl is standing beside him at the Bruno Mars concert.
As we previously reported, Ashton gave a Brazilian photog the cold shoulder when asked if Demi was okay -- giving no answer.

Ashton Kutcher had no answer when asked if Demi Moore was okay following her nitrous oxide-induced medical emergency -- hopping wordlessly into a car beside a blonde mystery woman Tuesday night.
The video was shot as the actor was leaving a nightclub in Sao Paulo, Brazil -- an agency photog asks, "Is Demi okay?" ... and Ashton keeps mum, piling into an idling vehicle with two acquaintances, one female.
Ashton has yet to speak out on Demi's condition. The two split in November.
Health Crisis ...
Inhaling Nitrous Oxide

Demi Moore's friend called paramedics Monday night after the actress inhaled a dangerous amount of nitrous oxide ... TMZ has learned.
Sources tell TMZ ... one of Demi's friends who was at her home told emergency workers Demi was doing whip-its. A whip-it is a street name for a type of nitrous oxide inhalant.
The friend said she became upset when Demi had a reaction to a whip-it and lapsed into semi-consciousness.
It appears Demi had symptoms of a seizure -- after inhaling the nitrous.
A whip-it is not a common drug among people of Demi's age and social status. It's typically used by younger people who are looking for a cheap thrill.
