Dream Pop Star Collaborations: 15 Team-Ups We Want To Happen

1. Justin Bieber & Ed Sheeran

Neither Justin or Ed has said anything concrete about a potential team-up, but the 'Boyfriend' star DID say Ed's practically the only star on his iPod these days. With Bieber working hard on new music right now, and Ed's penchant for writing hits to other people, it doesn't take a VAST leap to imagine this happening. tPicture: Instagram

2. Calvin Harris & Iggy Azalea

Iggy's year has seen her come one of the biggest female stars on the planet, thanks to her worldwide smash 'Fancy'... and featuring on Ariana's 'Problem' of course! Team her up with one of the biggest producers around right now and you've got yourself a surefire hit! Picture: Getty

3. Lorde & Taylor Swift

These two self-confessed BFFs have been very vocal about their admiration for each other in recent times. Just imagining their voices on the same record makes us VERY excited indeed. Make it happen ladies! Picture: Getty

4. One Direction & 5 Seconds Of Summer

This one's a long shot but, knowing how good pals these nine chaps are, it totally COULD happen! What do you reckon boys? Picture: Instagram

5. Ariana Grande & Ed Sheeran

Both of these stars have KILLER voices, and great songwriting sensibilities. If there was ever going to be a sleeper hit to knock both 'Problem' and 'Sing' out of the water... it's bringing these kids together for a track! Picture: Instagram

6. David Guetta & Miley Cyrus

At the Summertime Ball this year, after his incredible closing set, David admitted he has the "perfect" song for Ms. Cyrus. Well Miley, what are you waiting for? The world's BIGGEST DJ has a song for you... go and get it! Picture: PA

7. Cheryl Cole & Jessie J

Both Cheryl AND Jessie have new albums coming later this year, and between Jessie's high notes and Cheryl's knack for an incredible pop tunes, this dream team-up could be VERY special indeed. Picture: PA/Getty

8. Ella Henderson & Union J

The Union J boys and Ella were together on The X Factor back in the day, and have remained friends ever since. The lads are also keen to feature a female singer on one of their records one day. Are you thinking what we're thinking? Picture: Getty/Splash

Jessie J and Nathan Sykes Summertime Ball 2014

9. Jessie J & Nathan Sykes

After their INCREDIBLE Summertime Ball team-up on 'Calling All Hearts' in June, fans can't wait to see more of Nathan Sykes. So why not let these kids get in that recording studio and lay us down a nice slice of pure pop? Picture: PA

Justin Bieber And Ariana Grande Instagram

10. Justin Bieber & Ariana Grande

This one's a bit of a cheat... because we already KNOW this pair have been in the studio together. Ariana says they're waiting for the right time to treat fans to this team-up, but c'mon Ms. Grande... how long does everyone have to wait? #BringIt

11. Miley Cyrus & Pharrell Williams

This pair have already worked together BEHIND the mic, thanks to Pharrell's hand on Miley's incredible album 'Bangerz', but we reckon the Smilers want a full-blown duet from this superstar duo.

12. John Newman & Naughty Boy

Hold on, these two HAVEN'T worked together yet? Nope, and it beggars belief! SOMEONE GET THESE TWO IN THE STUDIO NOW!

13. Disclosure & Jess Glynne

This one seems like a match just WAITING to happen! After Jess' incredible success this year on tracks by Clean Bandit and Route 94 (as well as her new solo stuff!), and news Disclosure are working on a new album, this one would come as NO shock!

14. Kesha & Calvin Harris

Kesha and Calvin are BOTH steadily working away on new music for their next records and putting the 'C'mon' singer's vocals over a Calvin beat just makes SENSE! Right? Picture: PA

15. Little Mix & Timbaland

The Little Mix girls have been VERY vocal about their admiration for Timbaland, and with the girls' amazing classic R&B girlband sound, a Timbaland produced record could be something INCREDIBLY special. Picture: Getty
