Is This Legal?

How old is Selena Gomez? I have a serious thing for the favorite wizard of waverly and I don't care if it gets me thrown in jail or in a fistfight with Bieber. Don't get me wrong, I have no beef with the Bieb. "Baby" is my shit, I could sing you every world but I'll throw the fuck down like Madison on Million Dollar Listing if it gets me the love of Gomez. But then there's still the age factor, you say? I might actually take a tip4tit and not ask how old she is. Use the Mark Sanchez defense of "well if she's in the bar and it's 21+ then she's gotta be 21, right?"
