Katy Perry and John Mayer 'in love'

KATY Perry and John Mayer are "in love".
The 'Dark Horse' hitmaker - who recently rekindled her romance with the 37-year-old singer-songwriter - reportedly went on a double date with friends Allison Williams and her fiancé Ricky Van Veen where the new couple seemed very loved-up.

A source shared: "They are in love. They missed each other.

"They seem very happy about being back together again."

The couple is now working on balancing their work commitments with their personal lives.

The source added to People magazine: "They have to make time for each other and figure out how they can be together in a smooth relationship."

Meanwhile, another insider recently revealed that the 30-year-old singer is giving John "another chance".

A source said previously: "Katy is giving John another chance because she feels like there could be something there."

The pair dated after Katy divorced comedian Russell Brand in 2012, but called an end to their romance in February 2014, shortly after releasing a duet together titled 'Who You Love'.

However, friends of the 'Fireworks' hitmaker are concerned she is moving too fast, following her split from producer Diplo at the end of 2014.

The source added: "Katy and John are back together.

"John pursued Katy relentlessly because it drove him crazy seeing her with Diplo.

"Although her friends have warned her to be careful, she is already ignoring all of the red flags. She is not listening to anyone and is going into this full force."
