MOST brides are keen to look their best on their big day — but this lovestruck couple took their matrimonial garb to a new extreme in Beijing.

The couple added gas masks to the more traditional wedding outfits before posing for a number of shots around the Chinese capital.

It’s believed the pair took the shots to raise awareness of the city’s poor air quality which has grounded planes and closed roads.

Chinese scientists have warned the country’s toxic air pollution is now so bad that it’s slowing photosynthesis in plants — and potentially wreaking havoc on the country’s food supply.

Beijing and many northern provinces have spent the past week blanketed in a dense pea-soup smog that’s not expected to clear until tomorrow.

We are still yet to see the lifting of the gas mask and the first kiss.
