The I'm a Celebrity... Get Me Out of Here! contestant and former Pussycat Doll premiered the clip for her debut solo single 'Yesterday'.
The track - which is available to download from December 3 - marks her first major solo release after the Pussycat Dolls disbanded in 2010.
Roberts, who is signed to Cherry Red Records, is expected to release a follow-up single and full album in 2013.
Adam Velasco, head of Cherry Red Records, said: "Cherry Red is delighted to be working with Ashley on this exciting single, we hope to give her music the success it deserves."
The singer recently told Digital Spy that she is "excited" to release a solo track, adding: "It's pretty awesome to have a new song, but it's going to be weird to be in the jungle when it's released in the UK."
