Jennifer Lopez and Ben Affleck's relationship seems like a lifetime ago, and both have moved on since their 2002 romance. However, when J Lo stopped by Watch What Happens Live on Thursday night, she still had a lot to say about her ex — especially about how she helped transform him. "I did kind of, like, say, 'You need to be, you know, you're a movie star! You should wear a suit, you know? You should do this with your hair," she revealed. And he liked it. "He was into it. He didn't do anything he didn't want to do. He had some good fashion moments when he was with me." When it comes to comparing her exes, she didn't hold back there, either. When host Andy Cohen asked if actors, musicians, or dancers were better in bed, she replied, "I have to say that in my limited experience, I would have to say anybody involved in music, so I would say singers and dancers." During her candid appearance, J Lo also opened up about her alleged "feud" with Mariah Carey (which she claims isn't true), how she just "jumped on" Josh Lucas during her all-time favorite love scene, and how she still loves and is good friends with exes Cris Judd and Casper Smart.
