Chad Ochocinco and Cheryl Burke: Dating with the Stars?

Are Dancing with the Stars tandem Chad Ochocinco and Cheryl Burke dating? Even engaged? That's the rumor after the NFL star put a ring on it.

No, seriously, he did. The significance behind the sparkler he gave Cheryl, which she was rocking on Monday night's episode, is unclear, however.
Chad, who has also been seen kissing Cheryl on the lips in recent days, downplayed the bling, saying, "It's a thank you. It's a gift. A friendly gift."
"In my world, we tend to give those that we care about gifts. Why is it such a 'wow'?" The blushing pro dancer did admitted, "I fainted a little. A little concussion. [He] gave it to me in the trailer on one knee. And it's on my ring finger."Following Buzz Aldrin's elimination last night, Cheryl and Chad are through to the next round after three straight respectable dancers,jelling more each week.Does the twinkle in her eye hint at an engagement? Or at least love? Burke demured "You never know." The footballer said, for now, the dance floor "will be our aisle."Like Erin Andrews and Maksim Chmerkovskiy, also the subject of dating speculation themselves, these two have good chemistry, and enjoy feeding the rumors.While not confirming or denying any romance, the Cincinnati Bengals player, who changed his name from Chad Johnson in honor of his uniform number, 85, said:"She's certainly made me smile for seven weeks now."
What a charmer. Propose already, will you 85?
