Sports Illustrated swimsuit model Kate Upton and the artist and Ciroc spokesman formerly known as Puff Daddy were spotted making out in Miami last month and dining together in New York City this week, leading New York’s Daily News to declare that the two are “hot and heavy” enough to deserve a nickname: Diddyup! But what about Cassie? It was only last year that the singer was featured in a GQ spread titled “Diddy’s Girl” and just a few months ago that the two were seen house hunting in Beverly Hills. Well, that seemingly perfect relationship is apparently over, and it’s perfect timing for Upton, who has been tragically single since at least Valentine’s Day. Diddyup are 23 years apart in age.
