It has been reported that Katy Perry likes to splash her cash on John Mayer, and she's keen to help him fund his lifestyle - right down to his regular massages.
Onlookers have seen Katy getting her wallet out on several occasion - even to pay for gifts for herself, from John! According to the National Enquirer, a bystander saw this in action. "One time a street vendour approached them selling roses and John said he'd buy some for his lady, but when he reached into his pocket he didn't have any small bills. So Katy ended up paying for her own flowers!
"She frequently picks up the tab for their gas, travel expenses, dining - even his massages."
Rumours are circulating that John plans to propose after he was seen looking at engagement rings over the Christmas holidays - so hopefully he won't be asking Katy to chip in for that expense!
It's believed that Katy's family are happy for her to foot the bill for John, with her Mum allegedly saying "maybe he's a saver and not a spender". As long as John treats Katy sometimes, we think it's good that the pair share their bills.
An insider told the National Enquirer that the pair are so well matched, their relationship is built to last. "John is serious about Katy, that's for certain."He has never imagined settling down with someone, but he's infatuated with her. They have the same sense of humour, they love the same music, and they love to travel together, and of course, she's beautiful."
They added "Although John's got a reputation as a ladies' man, all of their friends completely approve because he's so dedicated."
Awwww, it sounds like he might be putting a ring on it soon! We do love a celebrity wedding, so let's hope that it's on the cards!
