NBA veteran Daniel Gibson's estranged R&B diva wife continues to busy herself with work as rumors abound about the dissolution of their three-year union.

Soulful songstress Keyshia Cole is teaming up with world-famous shoe designer Steve Madden to launch a second collection of her "eclectic and funky style" stilettos and platforms, set to soon hit stores across the country. The two previously launched a line together, which instantly sold out at all the stores carrying the shoes.

Keyshia Cole blasts Daniel Gibson on Twitter

"Keyshia is great to work with," Madden told Dr.Jays.com. "She brings fresh ideas to the table, and knows what girls want. It was a pleasure to work with her again. Music has inspired Steve Madden's designs since we launched the brand in 1990. Today, music is still one of our muses and our continued collaboration with Keyshia Cole is a natural extension of this inspiration."

If only the 32-year-old songbird could capture that same kind of vibe in personal life. Cole recently confirmed in a radio interview promoting the upcoming launch of her sixth album that she and Gibson no longer reside together and instead are now "co-parenting" their three-year-old son.

In addition, rumors persist the two may actually be headed for divorce court amid reports both may have been unfaithful. During her recent swing of interviews, Cole also told fans the Point of No Return entitled album would "sorta" be about man bashing.

Cole and Gibson were married in a lavish ceremony three years ago that at least partly played out on their then B.E.T.-aired reality show Family First.
