P. Diddy, 43, has reportedly started dating 20-year-old model Kate Upton and they were seen kissing during a recent night out. The 43-year-old rap mogul was apparently seen kissing the Sports illustrated Swimsuit Issue model - who confirmed in February she had split from Detroit Tigers pitcher Justin Verlander - at Miami Beach nightspot Club LIV late last month, where they partied in the VIP section at a bash being held by the 'I'll be Missing You' hitmaker. A source told the New York Daily News newspaper: "They were kissing, they weren't hiding it." The public display of affection was reportedly followed by a night out in New York last Thursday, with the rapper sharing an intimate meal with the 20-year-old beauty at Gemma in the Bowery Hotel. An onlooker said: "They were having dinner together." Diddy was most recently romantically linked with singer Cassie, and though they were seen house-hunting together in Beverly Hills in January, it is believed they are no longer together. A spokesperson for Kate insisted she and Diddy - whose real name is Sean Combs - are not romantically involved. They said: "They met once a year ago and there's no further relationship at this point."
