We bet we can guess why Kate Upton is all smiles while at Paris Fashion Week!
Dressed in black boots, dark pants and a colorful plaid sweater, Upton flashed her pearly whites for photogs while heading to lunch. The blond beauty completed her Parisian daytime look with a blue bag and dark sunglasses.
Kate is currently at PFW without her beau.
Last week, Upton stepped out holding hands with Chmerkovskiy, 33, who she's been quietly dating for a few months now. "It's important to them not to exploit their relationship," a source recently told E! News of the couple. "They're very low-key, because they don't want to attract the press. That's not what they're about."
"They go to the gym together a lot," the source added. "Fitness is something they bond over. They also go on a lot of late-night walks. It's romantic and they know that at night there's less of a chance they'll be recognized."
But Upton and Chmerkovskiy are taking it nice and slow. The source dished, "They're not moving in together yet. She's looking for her own place [in NYC]."
