Katy Perry seems to be 'very much back together' with Rob Ackroyd.
The 29-year-old Dark Horse singer wrapped up the European leg of her Prismatic World Tour on May 31 in London and she threw a bash celebrating the feat at the O2 Arena.
Apparently she was getting close to former flame Rob, the guitarist for Florence and the Machine, throughout the affair.
'Katy and Rob seemed to be very much back together at her party on Saturday night,' a source told British newspaper The Sun.
'They were inseparable, kissing, flirting and cuddling away in front of the roadies, celebs and friends at the bash.
'There were a fair few famous faces in the room but Katy and Rob only had eyes for each other.'
It is claimed the pair have been spending lots of time together of late, as they watched the FA Cup Final with each other last month and he has attended many of her gigs.
Rob enjoyed a fling with Katy back in 2012 when she'd split up from ex-husband Russell Brand.
Katy broke up with boyfriend John Mayer in February after nearly two years of dating following claims he cheated.
Shortly after this occurred she was romantically linked to music producer Diplo, but it is claimed their alleged romance is no more, as they didn't share the same relationship goals.
Apparently Katy has refused to let relationships, past or present, get her off track as all her efforts are being poured into putting on good concerts for fans.
'Katy is focused on her tour right now," a source told E! Online. "She is not allowing anything to distract her from it."
