Reece confirmed to fans that he was single again after 15-year-old Anais revealed in a message that the pair had parted ways, but said they are both "happy".
Anais told fans that the split was amicable, but admitted they no longer follow each other on Twitter.
She wrote: "I just wanted to clear the air and say that me and Reece are both happy, we did not end in horrible nor messy way. I understand that us unfollowing each other could seem pretty harsh. The truth is, 2016 is going to be a very big year for Reece and I. I have my exams coming up and need to work very hard on doing them to the best of my ability, whilst Reece is working extremely hard with Blake and George in New Hope Club. We both thought it would be best to go our separate ways and focus on working."
Reece followed up her message, tweeting: "Anais & I are over, I saw that she tweeted her fans.. been busy recently so didn't get around to telling you guys! I'm happy & ready to work!"

In December, Anais - who is the daughter of Noel Gallagher and Meg Matthews - actually dismissed speculation that her and Reece had split, telling everyone to "stop making up rumours."
She tweeted at the time: "Me & Reece are not over, we just are very busy at the moment and don't see each other as much as we would like! #stopmakinguprumours."
Stereo Kicks parted ways in July 2015 after failing to get signed by a record label following the release of their debut single.

While members of the band are still pursuing music, and some solo, Reece has formed a new band with musicians George Smith and Blake Richardson called New Hope Club.
The trio are signed to 'Can We Dance' hitmakers The Vamps' record label. New Hope Club are also supporting The Vamps on tour this year.
