Former Little Mix singer Jesy Nelson – who quit the band in December 2020, citing her struggle with anxiety – also congratulated her ex-bandmates with a post on her Instagram Stories.
Nelson, 27, shared a picture of Thirlwall, Edwards and Pinnock with their Brit Award framed with heart and clapping emojis.
Accepting the gong onstage Little Mix dedicated their win to all the British girl bands that went before them.
Pinnock said: "It's not easy being a female in the UK pop industry.
"We've seen the white male dominance, misogyny and lack of diversity.
"We're proud of how we've stuck together, stood our ground, surrounded ourselves with strong women and are now using our voices more than ever."

Thirlwell went on: "The fact that a girl band has never won this award really does speak volumes, so this is not just for us, it's for the Spice Girls, Sugababes, All Saints, Girls Aloud and all of the incredible female bands. This one's for you."
The winners at this year's Brits received two gongs – with a smaller statuette alongside their main prize to share with someone else. Artists Es Devlin and Yinka Illori designed the "double trophy" to promote acts of kindness.
It is the third time Little Mix have been nominated for the award. Girls Aloud and Sugababes were both nominated for the award twice, while All Saints and Spice Girls were both nominated once
Other female bands to have been nominated for the award include Shakespears Sister and Eternal.
Little Mix were formed during the Bootcamp stages of The X Factor in 2011 and went on to win the series.
