Stardust and Stephen Amell - surprisingly one of the longest running rivalries in the WWE - have crossed paths once again.

During a panel involving Amell at this weekend's Dallas Comic Con, Stardust crashed the party to include himself in the conversation, and get up close and personal with the 'Arrow' star.

Posted by WWE on Saturday, February 13, 2016

The two feuded over social media throughout this past summer, culminating in a tag team match at WWE's SummerSlam pay-per-view event (which Amell and his partner, Neville, won).

The feud, however, was put on hold a few weeks ago over eight-year-old cancer patient Elijah Mainville (a.k.a. honorary WWE Superstar Drax Shadow).

Both were involved in the 'Nicky Clan' campaign that helped support Mainville as he battled Stage 4 cancer.

But with Stardust's latest actions - the feud seems to be back on.

Just in time for WrestleMania season...
