did alex and dianna break up ?

When i first saw that picture i looked it again and i сказал(-а) by myself ''Wait a минута where is dianna ?'' So i wanted to ask the others alex fans..
Please tell me did they break up :) LOL i know that's mean but he's my biggest crush what can i do? u know that he's gorgeous and breathtaking so tell me how can't i get jealous ? Btw it's kinda funny but i have to admit that dianna is a great girl and she is amazing ! :)
