stablery: I thought I was wearing black shorts and flowers? Alexandra Burke and Pixie Lott opt for almost identical outfits as they perform at T4 On The Beach

By Sarah Bull

They are constantly having to come up with inventive new outfits for their various public appearances.

But today Alexandra Burke and Pixie Lott made the biggest fashion faux pas of all when they arrived at T4 On The Beach at Weston-super-Mare wearing virtually identical outfits.

While Alexandra, 21, took to the stage in tiny black hotpants, a pink bikini top and a T-shirt top with added flowers, Pixie went for a similar combination of a black playsuit with a flowered Hawaiian Lei.

But despite their very similar outfits, both Alexandra and Pixie wowed the crowds with their performances at the annual music event.

After her performance, Alexandra took to her Twitter page and said: 'OMG! T4 was amazing - I've had one of the best days of my life !! Thank u 4ur love and support! The crowd was on fire!! Xx'

The one-day music festival is in its sixth year, and has proved even more popular with fans keen to catch a glimpse of their favourite pop acts.

Organiser Cath Lovesey said: 'We first came to Weston six years ago and have come back every year - it's a fantastic venue.'

Since winning The X Factor in 2008, Alexandra's career has gone from strength to strength.

And now, with three number one single under her belt, Alexandra is hoping to break America with her new track Start Without You.

Last month, the star was spotted filming the video for the new track in Los Angeles - showing off her amazing figure in a pair of denim hotpants and a cropped red and white T-shirt.

Start Without You is produced by RedOne who engineered her previous top ten hit Broken Heels.

The song recently leaked on to the internet and was reviewed by one fan as a 'summer song in the vein of Boney M's Hooray Hooray It's A Holiday.'

Meanwhile, Essex-born Pixie performed a variety of her most famous hits including Cry Me Out and Mama Do.

As well as producing hit after hit, Pixie is also increasing her personality profile, and joined The X Factor judging panel earlier this week alongside Simon Cowell, Louis Walsh and Cheryl Cole.

Speaking about her role on the show, Pixie said: 'I am really excited to be one of the guest judges. It's a new experience for me and I'm looking forward to it.'

The Saturdays: The girl band treated fans to a variety of their famous hits, including new single Missing You

1,2,3...4? The band was missing Mollie King, who has been left on crutches after a horsefly gave her cellutitis

Other stars who attended the event included The Saturdays, who were performing without bandmate Mollie King, who is on crutches after contracting cellutitis when she was bitten by a horsefly.

But the other four girls, Frankie Sandford, Rochelle Wiseman, Vanessa White and Una Healy, more than made up for Mollie's absence with a sexy performance in racy cut out T-shirts and bikini tops.

Before the band's performance, Mollie tweeted: 'So so sad I can't make this wkend! If I was able to sit up I would be there in a flash, but I have to lie down with my foot up! :-( So sad!'

And the feeling was most definitely mutual - with all of Mollie's bandmates tweeting that they were desperately missing her from the T4 On The Beach stage.

Eye candy: JLS wore a selection of coordinated outfits as they took to the stage accompanied by a chorus of fans' screams

Sexy lady: Ellie Goulding was the second act of the day, much to the delight of the fans

And while the male members of the audience were undoubtedly enjoying the abundance of pop princesses, male eye candy was provided in the form of stars including Dizzee Rascal, Taio Cruz and JLS.

JLS wore coordinating outfits of grey, white and red as they bounded onto the stage and performed a series of energetic dance routines.

But the pressure of performing in front of thousands of fans at the event got a bit too much for Jedward, aka John and Edward Grimes.

During a particularly difficult move in their Ghostbusters routine, Edward,18, landed awkwardly on his left foot and was rushed to hospital in an ambulance with what is believed to be a broken leg.
