The girls will be taking to the stage when the music awards return next month, along with the likes of James Bay, The Weeknd, Jess Glynne, Coldplay, Justin Bieber and even Adele.
That's one star-studded lineup, right?
Adding Little Mix to their list of acts that will be performing live on the night, the BRITs official Twitter account tweeted: "That noise? Oh, that's just #mixers celebrating that @LittleMix are performing at #BRITs 2016!!! #BRITsLittleMix
Meanwhile, Little Mix's account revealed Jesy Nelson was the first of the group to find out the exciting news and had messaged Perrie Edwards, Jade Thirlwall and Leigh-Anne Pinnock telling them to check their emails and, obviously, put the date in their diaries.
The girls shared a screenshot of Jesy's messages with fans. They read: "I can't stop crying. Omg. Read the email. Read the email. Guysssssss. Read it. Read it."
Tad excited, are we?
Jesy and Jade also took to Instagram to share how pleased they are, explaining it had been a dream of the group to finally perform at the BRITs one day.
Jade told fans: "I got a call from Jesminda yesterday asking if I'd checked my emails...because we're only performing at the bloody BRIT AWARDS!!! Had a good old sob down the phone followed by all of us freaking out on our group chat, getting all teary and soppy. We can't believe it. Every year we watch The Brit Awards and say 'imagine if we got to do that' and here we are."
Jesy, meanwhile, said: "So last night we got told that this is happening! I cannot tell you how much I sobbed like a rite old cry baby, it has been our dream for 4 years to perform at the Brits and I cannot actually believe we are now finally doing it!!! We have the most insane fans and we wouldn't be here if it wasn't for you guys!"
Hinting at a great show, she added: "We love you so bloody much and we cannot wait to show you what we have in store."
