Disney character Hannah Montana, and her off-screen alter ego, American starlet Miley Cyrus, have a following among celebrity offspring in the UK, too, it seems.
James Nesbitt and Jason Donovan and their excited children negotiated a 2,000-strong crowd of enthusiastic teens waiting to see their idol at the Leicester Square premiere.
And when the 16-year-old heroine made her appearance on the arm of her father country singer Billy Ray Cyrus she didn't disappoint.
Miley looked the picture of grown-up sophistication as she greeted fans in a sparkling silver mini-dress and four-inch heels.
The enthusiastic reception, following a similar reaction in Italy, underlines the appeal of the TV series and its big-screen debut.
By day Miley's character is Hannah Stewart, a mousey, anxious US teen worrying about spots, boys and the usual adolescent problems.
When she dons a blonde wig, however, she becomes Hannah Montana, a super-confident, super-successful singing star.
The concept is so successful Miley has earned £7 million to date through CDs, videos, computer games and albums based on the series.
