According to a source, the Dancing With The Stars couple definitely have a strong bond, but at this point, the relationship between them is strictly platonic.

"Some believe it's unlikely the two are romantically involved, since there is quite a large age gap between them. Reports say that their relationship is that of an older brother-younger sister type and their interactions are similar to how Mark Ballas treats his teenager partner Said Robertson," a source revealed, according to an Oct. 5 report by Inquisitr.

Last week the pair scored a perfect score of 40/40 with a Singing In The Rain-inspired dance. This week, in tune with the Most Memorable Year of Your Life theme, Mota and Hough will channel Mota's experiences with cyber-bullying.

"It's not about bullies themselves, but understanding why bullies are they way they are," Hough explained in his TV Guide blog.

Hough went on to explain how cyber-bullying affects the pysche, and why people let it happen. For example, he said relying on peer feedback on social media - like retweets and favorites - is all external, and therefore affects how adequately one can control their happiness.

Mota got her start on YouTube after experiencing bullying online. Through her video blogging, Mota turned a bad situation into a positive one, sharing beauty tips and tutorials with fans, and making a name for herself all on her own.
