Fantasia Barrino is desperate to make it work with baby daddy Antwaun Cook and RadarOnline.com has exclusively learned the singer is green with envy when it comes to his ex's relationship with his family.

Just one month after Fantasia had a baby with boyfriend Antwaun Cook, a pal close to the former American Idol winner exclusively tells RadarOnline.com that he's been cheating on her — even before she was pregnant!

"Antwaun has been cheating on Fantasia all along, just like he cheated on his wife with Fantasia," the source said.
