And now The Sun Online can exclusively reveal they were both messaging the same woman, Teddy Edwardes, behind each other’s back.
The Love Island star, 25, and the musician, 27, both sent private DMs to Teddy before ending their romance.
Events promoter Teddy tweeted about the tricky situation, although she didn’t name the two women.
She asked her followers: “I’ve got a girl and her girlfriend in my DM’s but neither of them know the other is doing it.
“When do I break the news or do I carry on and mind my business? .”

Days later she wrote the cryptic post: “How have I been single 5 minutes and already become centre stage of every lesbian drama? Just let me lesbian in peace for gods sake.”
A source said Megan’s OTHER ex Demi Sims, 23, told Chelcee that Megan was messaging Teddy.
Meanwhile, Megan has hinted Chelcee didn’t make her ‘feel good’ in their relationship.
She appeared to hit out at Chelcee in a post on social media by sharing a quote that said: “Reminder: Relationships are supposed to make you feel good.”
Former stripper Megan was last pictured with the songwriter Chelcee, who has penned tracks for superstar Kylie Minogue, arriving back in London after a trip to LA together.
They had also been snapped at the Women’s Super League trophy in Manchester City’s Etihad Stadium last month.
It came shortly after Megan’s fling with Towie star Demi after meeting on E4 show Celebs Go Dating.
A music industry insider said: “They got on really well and enjoyed a brief romance, but decided to call it a day earlier this week.
“Both were a bit upset about it, but remain pals. Chelcee is throwing herself into her music projects and concentrating on recording new tracks at the moment.
“She is working on a music video so that is taking her mind off her love life.”
Meanwhile, Megan, who has recently ditched her signature blonde locks to go brunette, is working with High Street lingerie brand Ann Summers.

Speaking about her sexuality earlier this year Megan, who dated Wes Nelson, 21, on Love Island, said: “I think long-term I would get with a woman, but it’s hard.
“I just felt like I needed to get with a guy because society said so but after the s*** I’ve been through, I just want to see how it goes with a woman.”
The split came just weeks after Megan gushed about Chelcee, telling Metro Online: “It is definitely different [dating girls to guys].
“My whole life I’ve never really had a relationship with girls, like I said on Celebs Go Dating.
“And I’ve had, sexual experiences with girls and I’ve had one night stands with girls, but I feel like this is actually me.
“I’ve never felt so comfortable in my life, I feel like I’m finally where I should be. I’ve never felt as comfortable with someone.”
