She's keeping her chin up!

Kendra Wilkinson stepped out in L.A. yesterday with a huge grin on her face, and if we didn't know better we would never have been able to tell that she's going through relationship drama with husband Hank Baskett!

The former Playboy playmate wasn't wearing her wedding ring, so we think the couple is headed for splitsville, but it could all be an elaborate PR stunt to attract ratings for her reality show Kendra On Top. If you believe the rumors, her football player hubby hooked up with a transsexual model he met online shortly before the blonde beauty gave birth to their second child.

The reality star must figure looking good is the best revenge, because she has already shed all the baby weight she put on while pregnant with her daughter!
