Nicola shared a new picture of herself and her former Girls Aloud bandmate yesterday (29 January), which was taken during a night out.
The Liverpudlian star, 28, is best friends with 30-year-old Cheryl and posted the snap on Twitter as part of the site's 'Woman Crush Wednesday' trend.
Alongside it, Nicola commented: "Bff <3 #wcw @ladyccole."
Along with Kimberley Walsh, Cheryl and Nicola formed close friendship after landing their places in Girls Aloud during TV how Popstars in 2002.
The trio and fellow bandmates Nadine Coyle and Sarah Harding enjoyed huge success together before announcing Girls Aloud's split last March.
It's great to see Cheryl and Nicola are closer than ever, however it doesn't appear the WCW feeling is mutual - as Cheryl posted a snap of Khloe Kardashian as her girl crush!
