Johnny Borrell is dating Sting's daughter.
The Razorlight rocker - who has previously romanced Kirsten Dunst and was linked to 'Harry Potter' star Emma Watson -accompanied Coco Sumner to The Music Industry Trust awards at London's Grosvenor House on Monday (03.11.08).
A source said: "Johnny and Coco had a great evening. They were laughing and joking together and seemed totally relaxed."
It has been claimed Johnny, who at 28 is 10 years older than Coco, had been trying to keep their fledgling relationship a secret until the pair decided to step out together.
Budding musician Coco and her band I Blame Coco have signed to Island Records, the same label as her father Sting – real name Gordon Sumner.
The group are expected to release their debut album next year.
Sting recently revealed he is proud of his daughter's desire to pursue a career in music.
He said: "It is lyrically very sophisticated and musically wonderful - she is the real thing. She is really interested in reggae. I am very proud of her."
