First it was Katy Perry, and now Pixie Lott can be added to the list of famous West Ham fans from the world of pop music.

While the American delighted Hammers supporters by posing in club-themed underwear, the 23-year-old English singer's Claret and Blue colours were revealed on BT Sport on Thursday night when she was presented with a home shirt with the word 'Pixie' printed on the back.

Pixie is usually spotted in glamourous outfits on stage and at fashion events around the globe, but she looked delighted with her new kit handed over by Life's a Pitch host Des Kelly.

'Over the moon with my new surprise treat,' Pixie said on Twitter afterwards, 'thank you so much West Ham and BT.'

Pixie was born in Bromley in Kent but moved to Brentwood in Essex aged 13, so it appears Charlton's loss has been West Ham's gain.

England fan: Pixie was spotted in this Three Lions shirt, with 'Lampard' on the back, in 2010

Hammer blow: Pixie's favourite team have spent most of the season fighting against relegation

Happy Hammer: Katy Perry is another famous West Ham fan from the world of pop, as these pictures prove

She was on the show to promote her new single 'Nasty', and performed an acoustic version of her 2009 hit 'Cry Me Out'.

And her new look might boost sales in East London and Essex, although its nationwide appeal might be somewhat limited. 

Kelly tweeted: 'Ms Pixie Lott in what some consider her most glamorous outfit yet. Some, I said.'
