[@duaiqbal1057]

I love Alex and Sierra. Alex: I like doing the shovel... For me it's the lawnmower... Chelsea is like a unique interviewer. She makes all the interviews fun and energetic... World Peace, Blueberries, Yogurt Land... Sierra and Alex are so cute together... The fact that they Sierra got to slow dance with Niall James Horan is like a dream come true. I loved the cover of Best Song Ever that they did. Sierra did amazing with Alex and shouldn't have gotten the negative votes. I hope they win.. I see great potential in them in the future :)
