X FACTOR star Myles Stephenson has secretly split from his long-term girlfriend after reaching the live finals.
The Rak-Su singer and his beau Rebecca Bignell had been "on a break" since late September after drifting apart to help him focus on the ITV show.
But now Myles is fully single after the couple - who had been friends for eight years and an item since April 2016 - permanently parted ways on November 7.
A source said: "They agreed to some time apart as his head was not in the right space and it was unfair on her.
"They've been on a break since then, but last week they agreed it just wasn't right and that they would split permanently.
"But his ex-girlfriend is still very much part of his life and they are on good terms. They still talk on a daily basis as friends.
"Myles actually invited her down to the show last weekend."
RnB foursome Rak-Su steamrolled to the finals after emerging as front-runners when they impressed the judges with original song I'm Feeling You.
Mentored by Simon Cowell, they comprise Myles, Rak-Su J, Ashley Rak-Su and Mustafa.
And Simon's not only judge impressed, with fellow judge Nicole also giving the group the seal of approval.
And on October 30 Cheryl revealed herself as a fan after posting the gushing tweet: "Just saw last nights Xf !! Rak-suuuuuuuuuuu come thru boys! Yessss! Obsessed."
After making it through Judges' Houses to the live finals, Rak-Su remain in the competition with rival groups The Cutkelvins and Sean and Conor Price.
On Saturday the boys were branded 'disrespectful' for adding their own rap lyrics to a George Michael song during the show dedicated to the late singer.
