It hasn't been that long since Maddie and Mackenzie Ziegler left the reality show "Dance Moms," and they seem to be busy with a lot of projects lately. However, Mackenzie has captured the attention of many fans online after rumors started circulating that she is already dating.

The rumors started making rounds online after Mackenzie uploaded a photo of her and 13-year-old Canadian singer/actor Johnny Orlando on her Instagram account. Although there is nothing romantic about the photo, it is noticeable that both young stars are staring cheerfully at each other. The rumors even intensified with her caption, "We up to something." However, it could really just mean anything.

Mackenzie is not the only one who shared her and Johnny's photo, the Canadian singer also uploaded another version of his and her photo together on his Instagram account. His caption reads: "Thanks for stopping by our Pittsburgh show @officialmackzmusic. Expect to see something from me & mack soon." Based on his caption, it is highly likely that they are just working on a project together — maybe song collaboration since they are also both singers and YouTube personalities.

In other news, Mackenzie, together with older sister Maddie, recently became hosts at the  TigerBeat's Official Teen Choice Awards Pre-Party Sponsored by NYX Professional Makeup and Rock Your Hair. This is just one of the sisters' numerous projects and commitments before heading to "Chandelier" singer Sia's tour.

Aside from their hosting gig, the sisters have reportedly teamed up with Clean & Clear skincare company for a back-to-school campaign. They were selected because of the growing popularity of the siblings after starring on "Dance Moms" and Maddie's stint on Sia's video "Chandelier." Meanwhile, aside from dancing, Mackenzie is also focusing on making her singing better.

There are also new rumors that Mackenzie may return to "Dance Moms." However, there is no confirmation from the show or network yet.
