Katy Perry appears to have jetted off on holiday with Diplo.

The 'Birthday' hitmaker, who ended her brief romance with the music producer last month after they were linked at the Coachella Valley Music & Arts Festival in Indio, California in April, sparked speculation she has reunited with the DJ after they posted similar pictures of themselves lying in the same hammock in a tropical location on Instagram.

The 29-year-old singer uploaded a photograph of herself looking happy and relaxed in a red and white patterned hammock on Sunday (08.06.14), with the caption: ''Swaying on the hammock under mango trees, fresh freckles on my face, everything irie ?? (sic)''

Just hours earlier, Diplo, real name Thomas Pentz, shared an image of himself lounging in the same outdoor swing, but deleted it after his fans guessed he was with Katy, who is currently enjoying a break from her 'Prismatic World Tour' before she kicks off the North American leg on June 22.

A source previously told InTouch magazine that the duo called off their relationship because it was moving too quickly and Diplo, 35, wanted to introduce the 'Roar' singer, who was reportedly all over Florence and the Machine guitarist Rob Ackroyd at a party in London last week, to his family.

The insider said: ''Diplo broke up with her because she does not want to be in a serious relationship. She's doing OK and not too sad about it. They wanted different things.''

Katy - who split from Russell Brand in 2011 after 14 months of marriage and called time on her on/off relationship with John Mayer in February - recently admitted she isn't ''super strict'' about her sex life.

She said: ''I'm not like Professor Higgins with my sex life. I'm not super strict. For me, the most important thing about sex is connection.''
