That's my girl! Lady in lace Cheryl Cole raises a toast to BFF Kimberley Walsh at book launch party

They've been firm friends since becoming bandmates in Girls Aloud over 10 years ago.
So it was only right for Cheryl Cole to leads the toasts to her BFF as they celebrated the launch of Kimberley Walsh's autobiography.
Dressed in red lace, Cheryl, 30, honoured her former bandmate as they marked the upcoming release of A Whole Lot Of History at the ME London hotel on Monday night.

Cheryl went for ladylike elegance in a £815 red lace dress by Lover, which she teamed with a pair of tan high-heeled sandals.
Meanwhile, Kimberley, 31, dared to bare in a plunging navy jumpsuit, completing her look with a pair of unusual patterned Sophia Webster heels.
Joining the pair at the five-star hotel in Aldwych was their former Comic Relief Mount Kilimanjaro climbing pal Denise Van Outen.

TV presenter Denise has remained good friends with Cheryl and Kimberley since they hiked the mountain in 2009.
Last year, Denise and Kimberley both ended up in the final of Strictly Come Dancing, eventually losing to Louis Smith.
Following her evening, she tweeted on the way home: 'Huge congrats @KimberleyJWalsh can't wait to read your autobiography 'A whole lot of history' xxx #proudmate.'

Missing out on the event was Kimberley's former Girls Aloud bandmates Nadine Coyle, Sarah Harding and Nicola Roberts.
According to her Twitter, it looked like Nicola was busy working in the music studio, while Nadine is believed to be at home in Los Angeles, currently preparing for the birth of her first child.
Nicola did tweet Kimberley: 'Miss Walsh, I hope you're having a lovely time at your book launch tonight.. Love u xx.'

Although Kimberley is close with Cheryl and Nicola, she has been open about her working relationship with Sarah and Nadine.
In an interview on This Morning earlier on Monday to promote her book, she said: 'It’s a funny one, you have got five people thrown together in a group... sometimes you work together really well.
'But in terms of socialising with them every night and going for drinks every night and really connecting on a really personal level, it’s not going to happen with all five. And that’s all I meant by that.'
