Rumours are rife that Katy has found a new kissing partner in the shape of 28 year old singer/songwriter Josh Groben

Celebrity blogger Perez Hilton has revealed that sources close to both celebrities have tipped him off, saying that the couple have been trying to keep their relationship a secret.

Katy recently vowed to remain celibate for at least a year after her previous relationship with Gym Class Hero, Travis McCoy, came to an abrupt end.

Katy has also been linked previously with Paris Hilton’s ex-squeeze Benji Madden although this was always denied.

Katy is currently touring the US with her ‘Hello Katy’ tour which comes to the UK later this year.

Classical singer/songwriter Josh Groban’s previous relationship with actress/model January Jones ended in 2006 and he has been classified as ‘single’ ever since.

Josh is most famous for his collaborations with some of the music world’s most notable performers from Barbara Streisand to Plácido Domingo. Grogan has previously been nominated for a Grammy and his four albums have all achieved multi-platinum status. He also appeared in two episodes of the US comedy series- Ally McBeal.
