The boy band member, who is believed to have been seeing the blonde model since May 2015, has reportedly already been introduced to the Oasis legend during Clapham Calling Festival, on July.
Reece and Anais, 16 and 15, couldn't look more smitten with each other on their Twitter photos.
However the young musician was forced to speak out against haters after he was belted with negative tweets about his new relationship.
He wrote: "Recently I posted a picture of Anaïs and I. I wasn't expecting you guys to react the way you some of you have, I really appreciate..."
"You that have wrote kind messages to me and Anaïs and to those that haven't been so positive I ask for you to please stop.
"It's really quite unnecessary. Some of the things that have been written aren't called for. Thanks again to those that have been supportive."
On early February 2016 it was announced that the couple had split. 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 2015, 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."
