If Olivia Ponton and Joe Burrow are, in fact, dating, the Sports Illustrated Swimsuit model isn’t kissing and telling … emphatically shutting down questions about her love life on Monday.

The 22-year-old — who’s been rumored to be hooking up with Burrow ever since she reported a burglary at his Ohio home back in December — was peppered with questions about the NFL superstar outside a Met Gala after party … but she remained mum.

She was initially jovial and warm with the pap in the New York City street — but as soon as the Burrow topic was broached, she shut down.

Of course, we all should have seen this coming … as Burrow and Ponton have done their best to avoid being seen out in public since the infamous break-in. In fact, they’ve only been photographed together once in the last half year … this past weekend in Miami.

The two were in South Florida for Formula One festivities … yet even when the cameras captured them in the same vicinity — they sure tried like hell to avoid being seen too close to one another.

So far, the only on-the-record statement anyone close to the two has made about their relationship is Olivia … when she told cops she was “employed” by the 28-year-old quarterback.

For Burrow’s part — he, too, has been tight-lipped about Ponton … even though he was also at the Met Gala on Monday.
