Cause she's lovable as all ****.
She's the sweetest. I've never heard any sane person say anything bad about her.

She's just flawless.

Because she's hot, nice, and classy!

Cause shes sweet and seems very normal.

She's a nice girl that makes catchy songs. How can you not like her?

She's cute.

And so do many more

Carly Rae Jepsen: She’s adorable and very pretty.

David Bekcham: Selena is the kind of girl you want to date your sons.

Lady Gaga: She is kinda centred on her job and she is an amazing girl.

Louis Tomlinson: Selena is gorgeous.

Liam Payne: What would I do if I was Selena for one day? Oh, my friend, you don’t even want to know.

Big Time Rush: We love her so much and we’d do anything she believes to support her.

The Wanted: We like to think she’s a fictional character, because no one is really that beautiful.

etc..

She's nice.

Because she's Justin's girlfriend.

of course. she was successful before dating him , so gtfo .

Nicki likes her too. Her cover of Superbass has 40 millions views on youtube. ^_^

Because even if you dislike her music, she is just such a genuinely nice person that there isnt really any reason to hate her.

Wait she's getting woman of the year?? From where and for what??

There's just nothing to dislike. She's in a league shared only by Taylor Swift when it comes to likeability in female teen stars. Both of them are genuine and who they say they are whereas the others, well...

Fro Glamour magazine. It's a big event with celebrities and politicians and they choose different women of the year. Selena's getting one because she's awesome, works actively with Unicef, Make a wish and the Ryan Seacrest foundation. She's getting honored out of the young stars, I suppose.
