The chart-topping girl band - Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall - joined Becky and British singer-songwriter MNEK for a songwriting session on Tuesday (26 August).
Teasing the collaboration, Leigh-Anne said: "Amazing session yesterday with the very talented @MNEK and @beckyhill very excited for this one."
And it seems like there'll be more creative collaborations on the way. Jade later teased: "Amazing writing session with @MNEK and @BeckyHill. #Smash as Becky so nicely put it we are #eggsofgood can't wait for the next sesh!"
In July, Little Mix apologised to disheartened fans after announcing plans to put their first US tour on hold to focus on their album.
Pop group Little Mix, who celebrated their three-year anniversary this month after successfully winning the eighth series of The X Factor in 2011, have been fitting in studio time around their hectic performance schedule.
Little Mix's collaboration is also a good step in the right direction for Becky, who rose to fame after reaching the semi-finals of The Voice UK in 2012.
Becky, who was mentored by Jessie J on the BBC One talent show, has since gone on to achieve considerable success. The 20-year-old featured on Rudimental's track 'Powerless' earlier this year and has shown off her unique vocals across UK festivals.
More recently, Becky scored a number one hit with Oliver Heldens on 'Gecko (Overdrive)'. The success made Becky the first Voice UK contestant to achieve a number one record.
