The 24-year-old singer believes the 'Stay' hitmaker should have a year off from her hectic schedule because her life revolves around her work and he thinks she deserves some time away from the industry to focus on herself.
Speaking to Digital Spy, he said: ''Honestly, she's so nice. She's very personable - we've not got a bad word to say about her.
''She did so well with her last record that she deserves a break from releasing an album this year. She's released single after single and I can't get enough of her music... but I had a glimpse of her schedule once and she works every single day.
''I thought our schedule was busy, but hers is just too much!''
He explained: ''I think it would be a midtempo track. She can do the dancing and we'll stand there.
''We could do the video at a carnival. She can be relaxing and we'll dress up as sea monkeys at the front of the ride just singing along.''
There's already an Oscars buzz surrounding this movie.
