Since splitting from Russell Brand after their 14-month marriage, 'Firework' singer Katy Perry has been linked to French model Baptiste Giabiconi and Florence and The Machine guitarist Rob Ackroyd. But it appears Katy is back on with country singer John Mayer.
The 'womaniser' has previously dated Jennifer Love-Hewitt, Jessica Simpson and Taylor Swift.
Katy and John have enjoyed brief spells together since Katy's split from comic Russell Brand in December 2011 but the pair were rumoured to have split last time because John did not meet her "high standards".
Standards aside the pair appeared to be getting cosy earlier this week, prompting rumours that they are now back on.
According to the Sunday Mirror the pair were seen hand in hand at Soho House, Los Angeles on Thursday night with a group of friends.
Showbiz Editor Dean Piper said: "I saw the pair cavorting together at a table with friends and they looked very much the happy couple.Katy and Kate Hudson were deep in conversation and John was golding Katy's hand throughout."
Meanwhile Katy's ex, Russell Brand has been rumoured to have swapped his all night partying antics for late night yoga sessions and the comedian is said to have been spotted entering a yoga studio at 2am and re-emerging at 7am.
