Is it possible to target one specific area?

I'm so happy with my body right now. I worked very hard to lose 25 pounds which I thought was too thin, so I gained 5 recently. My chest, butt, arms, face, and legs are exactly what I want but my stomach went from curvy and thin (my ribs were showing a bit) to slightly chubby. That looks sexy on some girls but I'm not that curvy to begin with unless I'm really thin. Is there any way I can just lose weight or tighten my core and not lose boob or butt fat in the process? I stopped running because my boobs and butt got too small, now my love handles and tummy are showing. Sorry for the long description.. just frustrated.
