Two of rock royalty's most famous offspring have apparently fallen for each other, reports Hello! magazine.

The late Beatle John Lennon's indie-rocker son Sean and 20-year-old model Elizabeth Jagger, daughter of Rolling Stones frontman Mick Jagger, are currently an item - and the romance has been confirmed by Elizabeth's mother, Jerry Hall.

"They are so in love," said Hall of the couple, who recently spent time at the Texan model's home. "We had all these incredible family sing-songs with him around the piano. Sean is adorable. He looks so like John now and he writes beautiful poetry."

Twenty-eight-year-old Lennon's past girlfriends include actresses Bijou Phillips and Leelee Sobieski, while Jagger had been linked with actor Michael Wincott, 26 years her senior.
