BOYBAND McFly set hearts a flutter when they came to Liverpool to film an episode of hit teen soap-favourite Hollyoaks.

The pop sensations are to make a surprise cameo appearance in the Channel 4 show in May.

The boys’ Hollyoaks debut saw them perform in the band night arranged by Justin Burton, played by actor Chris Fountain.

Viewers will see the chart-toppers take to the SU Bar stage along with resident musicians Josh Ashworth, played by Sonny Flood, and newcomer Hayley Ramsey, played by Kelly-Marie Stewart.

McFly frontman Tom Fletcher discovers true love was failing to blossom between Justin and Hannah Ashworth (Emma Rigby) and the singer takes it upon himself to intervene.

Fans have to wait until next month to watch the guest spot and find out whether Tom’s advice falls on deaf ears.

Series producer Lucy Allan said she was delighted to have the foursome at the Lime Pictures studios in Childwall.

She said: “The McFly boys were great to have on set and they all worked really hard.

“They caused a bit of a stir amongst the female crew as well.”

The group are made up of lead singer and guitarist Tom Fletcher, Danny Jones, Dougie Poynter and Harry Judd.

Bassist Dougie Poynter has followed in the footsteps of his pop singer girlfriend Frankie Sandford by appearing in Hollyoaks.

Saturdays star Frankie and her bandmates, who released a cover of'Just Can't Get Enough for Comic Relief this year, filmed a stint for E4 spin-off show Hollyoaks Later last year.

McFly also released a charity song for Comic Relief.

In 2005 they had success with a double A-side release of You've Got a Friend, originally by Carole King, and All About You.

The boys, who found fame as teenagers in 2004, have secured 16 consecutive top 20 singles, including seven hits which reached the top chart position.

They saw their self-penned debut album, Room on the 3rd Floor, go double platinum, giving them the title of the youngest British band ever to have an album debut at number one – a title they took from The Beatles. McFly also starred with American actress Lindsay Lohan in the box office hit, Just My Luck. McFly will kick off their latest tour, called the Up Close ... And This Time It's Personal tour, with support from American Idol runner up David Archuleta later this month.
