Exciting news for fans: it looks like there's more solo material on the way from both and . While Zayn's collab with is confirmed and dropping "soon", the Louis rumours all stem from one excitable .

"[I just finished a new song] with somebody really big from a boyband," Bebe told CBS Radio's Culinary Kitchen. "It's a really massive record. We just finished it and it's about to come out in a month or so and it's amazing. It's probably one of my favourite songs I've ever been a part of in my whole career."

Hmm. We know what you're thinking: there are many, many boyband stars Bebe could have worked with. But, when you consider Louis recently followed her on Twitter, and she followed him on Instagram... Yes. All fingers point to a Louis Tomlinson and Bebe Rexha collaboration (we hope).

While we await further news from Team Tomlinson, check out everyone the 1D lads have worked with on their solo material (so far).

Zayn really knocked it out the park by teaming up with for the Fifty Shades Darker soundtrack. Their duet, I Don’t Wanna Live Forever, hit number two on the Billboard Hot 100 chart and is nominated for Best Collaboration at the Radio Disney Music Awards.

snared Zayn for her track Freedun, which appears on latest album, AIM. Speaking to in September 2016, M.I.A. said, "It sort of takes me out my comfort zone but kind of takes him out of his a little bit as well. It just worked out."

If you haven’t heard Cruel, Zayn’s collab with , you’ve clearly been hiding under a rock since last summer. "We had this beat and this idea we were working on, and we sent it out to him. He totally crushed it, it was a really cool thing to be a part of," the duo told Fuse.

was the only one of Zayn’s collaborators to make it on to his debut album, Mind Of Mine, with their track Wrong. When the album dropped, Kehlani took to Instagram to congratulate her mate, writing, "I'm so damn proud of you. Enjoy the f*** out of your moment, thank you for picking me to the be collaboration on this. You're a goddamn STAR!”

’s NSFW Back To Sleep remix was given a little extra something with the addition of and Zayn’s vocals, back in February 2016. Calling it “the ultimate R&B song,” Chris wasn’t entirely overhyping the track, which is pretty great. But, again, definitely NSFW.

Louis hooked up with cake-throwing DJ on his first solo single, Just Hold On, and it definitely paid off. The track hit number one on the UK singles chart and its official video has been viewed almost five million times in the two weeks since its release. Perhaps even better than that, we all got to witness the start of a beautiful bromance, resulting in Steve being adopted by the Directioners.

Is there another EDM banger on the way from Louis? It’s quite possible, after the 1D star was pictured in the studio with Norwegian DJ , back in January.

Speaking to the Daily Star, Matoma said, “I remixed Perfect for One Direction and Louis wanted to do something so we went to the studio to connect and had some fun. My impression is he’s a passionate, talented person and a really nice guy.

“The big thing is that he is humble and down to earth so maybe something will come.”

Also spotted in the studio with Louis: , who you might remember from her featuring slot on The Chainsmokers’ track Roses back in 2015. Speaking to J-14, Rozes said, “It was really fun working with him, and he’s super-talented.

“We kind of dug into his life, what he’s up to. He’s obviously going through an emotional time and then recreating himself [as a solo artist], so it was fun to be his diary for the day.”

But will she be on his debut solo album? Time will tell.

While enlisted to sing a very special version of his track Mercy backstage at the 2016 American Music Awards, we’re hoping there’s more to come from this dream duo, with Shawn telling Capital, "I got a chance to speak to him recently and we are definitely going to write together.

“We are going into the studio as soon as we can get our diaries together and see what we come up with."

That was back in October. Diaries still full, guys? There are plenty of bank holidays coming up, you know…

In an Instagram Live video in February, confirmed that they were speaking to Niall about a collaboration, before taking to Twitter to ask him a very important question.

Note the “see you next week”. We’re impatiently awaiting further news on this one.

We got pretty excited back in April 2016, when it seemed like Liam had teamed up with and , on leaked track You. However, our excitement was short-lived when he tweeted, “Hearing that I’ve got a single out lol that’s a surprise to me. That’s a one take scratch demo I was writing with someone as an idea for them.

“Guess I need to guard my projects better… They don’t even let you finish these days. Just to clarify I do not have a single, what you just heard is something I get up to on a weekend.”

And that was the end of that.

In January this year, and Liam Snapchatted from the studio, though spent more time doing Family Guy impressions than letting us in on what they were up to. However, on the same day, Liam posted a Facebook Live video that was way more informative.

“This is the studio that I’ve been working in today. I’ve been writing a song, it’s been a lot of fun,” said Liam. “I’m hoping you’re going to like the music, it’s a little bit different, but it’s really nice.”

Now when do we get to hear it, boys?

In an unexpected Instagram post from frontman Preston, Liam was pictured in the studio with him and producer Sylvester Sivertsen, in November 2016. The caption? "Music!" To say we're intrigued is an understatement.

Disappointingly, Harry’s duet Someday with was never actually released, instead being recorded by !

When Chelsea Handler probed as to why the original version never saw the light of day, Meghan answered, "I don't know. Harry's team, they're just probably working on his album now. I mean my management is his management, so it's a little awkward and sweaty and he's watching this right now but yeah."

Maybe someday (sorry) we'll hear Meghan and Hazza make sweet music together.

While neither Harry nor have said anything about their working together, let the cat out of the bag when speaking to Radio Times.

“Last year I tried to work with Bruno Mars – didn’t hear anything back. Tried to work with – didn’t hear anything back. They literally didn’t return my calls,” said Robbie.

“Then I met Harry Styles in an airport. ‘Oh, you’re writing, Harry? Great, who with?’ He goes: ‘Well, I just spent a week with Bruno Mars, and I’m about to spend a week with Max Martin’.”
