Are Chad Ochocinco and his Dancing With the Stars partner Cheryl Burke heating up off the dance floor?

On Friday's Ellen DeGeneres show -- days after the Cincinnati Bengals wide receiver, 32, handed Burke, 25, a splashy diamond ring -- the two play coy on romance rumors.

When DeGeneres tells him she's heard they're an item, he playfully replies: "We are?"

Burke then chimes in, "Really?"

"We're not going to put labels on anything," she later adds.

Though they haven't had any romantic nights out, Ochocinco says they have enjoyed one meal together -- at "McDonald's."

But Burke says, "I don't consider that a date."

DeGeneres then orders Ochocinco to kiss Burke.

After giving her a peck on the cheek, he says: "I've been with her for seven weeks, for nine hours a day, every single day. I think I've spent more time then the average married couple with her.

"We fight and fuss," he adds. "I'm like, this is what marriage must be like. So I remember the Beyonce song 'Put a Ring On It,' so that's where the ring comes in."

What gift will he get Burke next? "I'm waiting for my Bentley next week," she teases.

Adds Ochocinco, "You should see the next gift. It goes on and on and on...."
