Sean "Diddy" Combs is gushing over ex-girlfriend Jennifer Lopez. During an interview with Access Hollywood Live this week, the 44-year-old rapper and media mogul was asked about J.Lo's signature asset, her bum, which she proudly shows off in her super-sexy new music video for her hit song "Booty." Combs gushed, "Oh my God. I'm so lucky to have that great woman in my history, she is one of the greatest I've ever seen. Show them J, go girl! Go girl!" Co-host Billy Bush asked, "Is Kim Kardashian even in the same conversation?" And Combs replied, "No way! No way. No disrespect to Kanye [West] and Kim but that thing right there, that thing right there is something special."
