The pair were pictured with blood streaming from their noses and down over their mouths as they sat dazed in the car moments after the accident, in Los Angeles, reported Daily Mail online.
The crash occurred after they left a studio following a long 'day and night' of recording and it was Will.I.Am who was behind the wheel of the 100,000 pound Cadillac that drove into a parked car.
Cole wiped away tears as her passenger side airbag failed to open and she was thrown headfirst into the dashboard.
Eye-witnesses said that Will.I.Am's airbag inflated and hit him in the face, which caused him to have a nose bleed, but Cole's injuries were slightly worse as she was left with bruising too.
After police were called out to the scene the Black Eyed Peas rapper was taken to the nearby Cedars Sinai hospital where he emerged later wearing a neck-brace.
Both of them took to Twitter to assure fans that they are fine.

"Car accidents are not dope. I am glad I am ok. Cheryl Cole (and I) were coming back from the studio but she and I are fine... Just a little whiplash," Will.I.Am posted on Twitter.
Cole also said that no serious damage was done to either of them.
"Don't worry me and (will.I.Am) are fine, promise," she wrote.
