When asked if he heard wedding bells in his future, the basketball star-turned-actor, 41, told UsMagazine.com Friday at the International Consumer Electronics Show in Las Vegas, "I hear them now. We've been honest about that conversation, and we've had it."
Still, the recent Dancing With the Stars contestant, who has been divorced from actress Vanessa Williams since 2004, said he's not taking the plunge just yet.
"I've failed in marriage before, and this will be her first marriage," he told Us. "So we want to make sure the foundation is laid in a responsible way where communication is had about what she wants from life as a woman -- whether she wants to have kids or go back to school -- whatever she wants to do."
Either way, the father of two said they already feel like family.
"Watching her and my kids bond over the holidays was really a gift to me -- I couldn't have wished for anything better," he told Us. "I told her, 'We're not married, yet, but you're like a stepmother to my kids.'"
