Mega-famous men aren't exactly known for their loyalty to women - witness Brad + Jen, Pete + Kate, and Ryan + Reese. And while no one would call Sean Combs a one-woman guy, he has managed to stick by Cassie, his protege in the record studio and also the photo studio. Cassie posed with Diddy on I.D., and now he's enlisted the pop starlet to model his relaunched women's line, Sean John. They sent us a sneak peek of their upcoming campaign, where Cassie tries out some high-waisted jeans. The good news: Cassie looks gorgeous, the line looks well-made, and we're pleased Mr. Combs hasn't abandoned the girl or the label. The bad news: Those of you shirking the high waist for fall might get frustrated. It's certainly possible, but you may feel surrounded.
