Pretty Little Liars star and all around resident heartthrob Keegan Allen and model, Ali Collier, are the picture-perfect couple. The pair was first rumored to be dating way back in April of this year, and instead of coming right out and confirming the news they let their pictures do all the talking for them. After all, a picture is worth a thousand words! And if their adorable Instagram pics could say anything, it would be how absolutely in love with one another the pair seem to be.
