The 'Purple Rain' singer is reportedly ''smitten'' with the 23-year-old British singer and the pair have been spending more time together in recent months.
A source told the Daily Mirror newspaper: ''Delilah is talented and gorgeous and it's little wonder Prince is so smitten with her. They have always been close but things have moved on recently.''
Delilah was spotted among a host of stars to who watched Prince perform with is band 3RDEYEGIRL at Ronnie Scotts Jazz Club in London on Monday night (17.02.14), but a representative for the 'Raspberry Beret' hitmaker insists there is no romance between the pair and Delilah is close with all members of the band.
A spokesman for Prince, 55, added: ''Delilah is a friend of everyone in the band and everyone loves spending time with her.''
Prince - who has been divorced twice - met Delilah after discovering a video she shared on YouTube, and the pair reportedly grew close when he invited her to support him on tour in Australia two years ago.
Delilah - real name Paloma Stoeker - first spoke about her friendship with the star in 2012.
She said: ''Prince called and said he was a fan of my work and invited me on tour. It was amazing.''
Describing the iconic singer as ''perfectly down to earth'' she added: ''We hung out together. He's a lovely person and we get along.''
