Katy Perry is blooming now more than ever especially since she was pictured getting close and intimate with a new boyfriend, according to Perez Hilton.

The "Dark Horse" singer is said to be getting hot and heavy with on-and-off boyfriend Rob Ackroyd. Katy and Rob had a fling previously back in 2012. The two were last seen during Coachella and after such, Katy Perry went on to date musical heartthrobs such as John Mayer and Diplo.

However, it seems like Katy Perry is ready to give the "Florence and the Machine" guitarist another chance after they were seen getting really romantic in Europe during the "Roar" singers Prismatic World Tour.

An observer who has seen the couple in Europe commented about the blossoming relationship of the two.

"Katy and Rob seemed to be very much back together at her party on Saturday night. They were inseparable, kissing, flirting and cuddling away in front of the roadies, celebs and friends at the bash," said the source.

The news of Katy's reunion with Rob Ackroyd comes after several tumultuous relationships the Grammy-nominated singer has had in the past. It can be remembered that the singer previously ended her famous relationship with notorious womanizer John Mayer. Rumours had been circulating that Mayer and Perry were supposed to tie the knot due to Perry's insistence, although Mayer did not feel the same way about marriage.

According to a report by E! News, the "Dark Horse" admits that she will write songs about her breakup with the "Your Body is a Wonderland" singer.

"There's no bad blood...But I'm sure there will be inspired songs," Perry dished exclusively to Cosmopolitan.

In response to the possible Mayer-inspired songs by Katy Perry, the acoustic singer said his say to TMZ.

"I have super strength for gang-ups...I'm fine. That's what you're supposed to do, man. You're supposed to write songs. You're just not supposed to tell everybody you're doing it," said Mayer.

Could it be that Katy Perry is getting back with Rob Ackroyd for a rebound relationship?
