导读：英国偶像团体女孩乐团成员们或许对于乐团的回归拖延了一段时间，但昨晚她们为了和粉丝们开玩笑，把一张神秘的图片贴在了twitter上。镜子中能看到四个女孩，但每个人的脸都被手机遮盖了。但是只要更仔细地观察，就会很明显地发现照片中的女孩们分别是Nicola Roberts，Cheryl Cole，Sarah Harding和Kimberley Walsh。
Girls Aloud may have put their group on the back burner for a while, but last night they teased their fans by posting a mysterious photograph on Twitter.
Four girls can be seen in a mirror, but each of their faces is covered by a mobile phone.
However on closer inspection it is clear that the girls in the picture are Nicola Roberts, Cheryl Cole, Sarah Harding and Kimberley Walsh.
The picture was posted by Nicola and Cheryl, who are the only two girls with official Twitter accounts.
Nicola, 25, was first to send the photo to her site last night along with the message: “Girls night in.. x”
And Cheryl, 28, quickly followed suit with her posting, which had the caption: “Love my girlies <3”
The picture adds fuel to the rumours that a Girls Aloud reformation is imminent, but one member was noticeably absent.
Nadine Coyle has spoken about a band reunion, however last night she either declined to join the girls in their slumber party or was not invited.
It is expected that the girls reunion performance will take place at next year's Olympics.
Nadine, 25, has always insisted there is no issue between her and her fellow bandmates, but the other girls have been more forthcoming and claimed they rarely speak to her since they went on hiatus.
It was rumoured last year that due to their strained relations with Nadine, the band were planning on reforming without her.
However these claims were denied by a spokesperson who said they had signed the deal for their next album as a five piece.
The picture appeared to tell a different story, and its mysteriousness suggests the girls may have been meeting to discuss the next step for the band.
While they are each embarking on separate solo projects, it has always been clear that the girls will reunite at some point.
Nicola is currently forging a successful music career and is about to release the third song from her debut solo album.
Meanwhile the other girls have decided to turn their hands to acting.
Sarah Harding, 29, who recently split with her DJ fiance Tom Crae, has recently finished filming her first major movie role in Run For Your Wife.
Former X Factor judge Cheryl meanwhile will make a cameo appearance in upcoming Hollywood rom com What To Expect When You're Expecting.
And Kimberley Walsh, 29, has just played the role of Prissy Polly in Horrid Henry.
