John Mayer used David Foster’s Instagram post about his daughter to hit on her.
The legendary music producer shared a picture of himself with his daughter Erin to celebrate her 35th birthday and captioned it: "One of the loves of my life and my fav daughter on this day!!! #happybdayerin #iloveyou (sic)."
And cheeky John, 39, decided to take the opportunity to show his appreciation for the blonde beauty, writing: "Can you put a good word in for me?"
Erin and David, 67, have yet to reply.
John’s flirty message comes just weeks after it was claimed that he had been on a few dates with Amy Schumer.
A source said: "Amy and John have been friends for years but they have been growing closer over the past few months. They are both completely down to earth, and that’s why they get on so well.
"It is early days but they have been on a few dates and she even shared a photograph of themselves on Instagram last month after they attended a comedy gig together.
"John is in the middle of a world tour and she is filming, which has made it hard for them to see each other. But they are talking a lot and they have been flirting on Instagram. They are definitely having fun."
Amy split from boyfriend Ben Hanisch in May this year after the pair dated for over 12 months.
The comedienne had previously admitted Ben – who she met on a dating app – was the perfect man for her as he wasn’t phased by her celebrity status.
