Yes.
ASK HIM! Who cares if you can't date, that's not the point of liking someone!
You wouldn't know. If Justin Bieber knows her and likes her, then yes.
Nobody really knows. And how the heck will anybody know what kind of girl he likes?
i don't know, it depends on if you think he likes you or not.
See I know she likes me, and she knows I like her. I need advice :(
If he likes someone else then it's doubtful he would date you. If you really care about him more than just a friend then you should let him know.
Talk to both of them about it. Make sure he knows that you and her are together, but let her know it is her choice who she is with.
He likes you that is what is important. it doesn't matter who else knows you.
huh!!
ask her out
You play it cool. Act as if you dont know he knows.
start talking to her and get to know her fisrt before anything!
