"Arrow" star Stephen Amell recently attended a WWE match that featured Stardust. While there, the latter approached the actor and challenged him for a fight. The two have been slamming each other on Twitter, but fans are speculating that all of those could just be for show.

Unfortunately, Stardust lost the match and was embarrassed over this so he approached Amell and started hissing at him, according to Tech Times.

Following the encounter, the "Arrow" actor and Stardust once again took their thoughts to Twitter. Amell used this as an opportunity to respond to Stardust's invitation for a match. The actor posted a collage of photos from the WWE match that featured Stardust threatening him.

"You tread carefully @StardustWWE - Or I'll be back," Amell captioned the photo.

One Stardust fan commented on Amell's post and wrote, "@StardustWWE is a better actor then @amellywood ever will be.

The "Arrow" actor seemed to have taken offense over this statement when he replied and corrected Stardust's fan who used then instead of than. He tweeted, "Than."

Meanwhile, Stardust also invited the actor, who plays Oliver Queen on "Arrow" to return to the WWE match on Monday night, Comic Book reported. As of late, it is unclear whether or not Amell will be back even just to watch his real-life nemesis.

In other news, "Arrow" season 4 has already been confirmed by The CW. According to the show's cast members, Oliver and Felicity's relationship will take center stage in the upcoming season.

However, this does not mean that their relationship will be all fun and game. In season 4, Felicity and Oliver's relationship could actually end.
