The songwriter has been dating the beauty for five months, but Delevingne is said to have called time on the relationship because of their busy schedules.
A source tells British newspaper The People, "Jake is very upset. Cara is a great catch and lots of fun. She definitely won't have any trouble finding a replacement for him.
"Cara's career is going so well so perhaps she's erring on the side of caution and concentrating on that. She weighed things up and with Jake's career taking off too, they didn't get to see a huge amount of one another anyway."
