I believe that currently she is single.

So She Said "I Love You & Your My BFF" But She Never Said I'm In Love With You & We shall Be together
Then She Mention Being There for Artie
But in The End We See The Three of Them Laughing & Together O_o

She's single.

I believe she is single at the moment because she is considering Artie as her friend
...and with Santana she says she loves her more than she ever loved someone else, and that there could be something else

So I think that currently she is single and in Season 3, she'll probably try to be with Santana [but I am not sure...]

I guess:)

Didn't she break up with Artie, and reject him in Prom Queen? And I think she and Santana are just BFFs.

I think she's single right now.

which makes her single.

Seems like she's single at the moment, lol.

I'm guessing she's single. I think they would have told us if Brittany & Santana were officially together.

She's single!!
