I would give Selena a charm bracelet with all of her paborito things; a basketball, a purse, two friends, an S and a G. That's what I'd probably give her.
A party on the beach. Dont ask me why, i just think that she loves a good party and i think she'll have fun on the beach... ok that was lame... i'd probably get her a pair of cute shoes or a braclet.
Selena Gomez would like an cooking a pron that sinabi stuff like "I pag-ibig Texas" or anything that has to do with Texas, friends, and or family put all together. (homemade so it makes her feel madami special)
if she wanted a gift i would buy her something nice like a kuwintas or something but if she didn't want anything than ....maybe i will still get her something!
