As the girls competed for attention on the runway of the Lingerie London show last night, they had the audience guessing which one was which.
With their voluminous blonde locks and trademark pouts the girls looked identical as they strutted their stuff in their kinky outfits.
Earlier in the evening, the ladies were wearing decidedly more clothes (just) on the red carpet at the event, held at Old Billingsgate Market in the capital.
But Abbey suffered a bit of a mishap as she tried to pull an Angelina in her thigh high, split red dress.
The model - married to England footballer Peter Crouch - flashed more than she intended as she struck a pose when she exposed her pants.
We doubt she's too embarrassed though, given what she took to the catwalk wearing.
Meanwhile, Sarah looked smoking as she took the plunge in in a daring blue dress.
Before the show, she tweeted: "Right guys wish me luck, off to strut my stuff on the catwalk, love you all and thanks for the support xxxxxxxxxxxxxxxxxxxxxxxx"
Sarah is in the middle of the Girls Aloud reunion madness, with tickets for their tour 'Ten' going on sale tomorrow at 9am.
