The pop star met the actress on the set of `What To Expect When You`re Expecting` when she filmed her cameo for the movie - in which she plays a talent show judge and she appears alongside Cameron - and she has a soft spot for the blonde beauty ever since.
Cheryl said: "Cameron is amazing, honestly I`ve got such a girlcrush on her. She`s such an amazing woman. It`s just so good to be doing new stuff."
The Girls Aloud singer is now keen to do more acting after working with Cameron and is open to any offers.
In an interview with Vogue.co.uk, she added: "I never had the confidence to do acting before, and I`ve said I could probably play myself quite well. It was brilliant, we`ll see what happens next."
The 28-year-old singer - who is no longer a judge on `The X Factor` after being fired from the new US version of the pop star search show - is busy diversifying her career and has just launched a shoe collection with online retailer StylistPick.com.
Although the stylish star has been offered fashion opportunities before she decided create her own footwear range now because the time just felt right.
She explained: "I`ve been offered a few fashion things before, and until now I`ve never really had the time. Now I`ve got a little more of that, it felt totally right. I`m a very hands-on person, I don`t just want to give my name to something and not be a big part of it. And who doesn`t want to design and play with shoes? - I feel like a little child - I just feel sick with excitement!"
